Romans 8

1 Everyone has sinned and is subject to eternal punishment in God's eyes, but when we have faith in Jesus we escape that penalty.
2 The purpose of the law is to make our behavior acceptable to God. The law of the Spirit takes precedence over physical laws because the physical laws have been tainted by sin. The law of the Spirit is still pure because Jesus keeps it.
3 This does not mean that the physical law is bad or evil, but sinful people simply can not follow it. Therefore God became like physical people in the person of Jesus to live a sinless life for us. He offered Himself as a sacrifice for us so that through our faith in Him the requirements of the physical law would be credited to our account, even if we were not able to follow them perfectly.
4 So we follow the law, not physically, but spiritually through our faith.
5 When we focus on physical laws we may lose sight of God. The Pharisees of Jesus' day were guilty of this. They followed the law to the letter, but they did this for prestige and power, not because they wanted to please God. It seems odd to me, but I have heard about Jews that claim to be atheists. They feel comfortable following many of the traditions of Israel, but they feel no need to follow the God of Israel. As another example, non-Christians will celebrate Christmas, even though they don't follow Jesus.

When we focus on God (the Spirit here) we seek to please Him first and foremost. When we seek to please God we obey the physical laws, not out of tradition, but because we love Him.

6 When we follow the law as an end in itself we will be subject to the punishment that it dictates. When we follow God, we will find no end to life and peace.
7 Whether the fleshly-minded man is lawless or (ironically) legalistic, he opposes God because he does not seek to please God. He seeks to please himself, others, or an inanimate code. He does not subject himself to God's law, which is to love and please Him.
8 He who does not seek to please God won't.
9 As Christians our focus becomes spiritual. In fact, God's Spirit becomes part of our lives. Everyone who has faith in Jesus receives the Spirit, but those who do not have faith will not receive it. When God's Spirit is in us we develop a personal and intimate relationship with God. This is something that pleases God because He made us to have a relationship with Him in the first place. Sin broke that relationship, but Jesus' sacrifice mends that relationship through faith.
10 Christians have a "split existence" in a sense. Our physical bodies are still contaminated by sin and are subject to the death penalty. However, our spirit becomes purified because of Jesus' sacrifice and because of God's Spirit indwelling us.
11 Even though our bodies are contaminated by sin, the righteousness of God in our spirit can still work through them because He is stronger than sin. The sinful body will eventually die, but God will keep our spirits alive and will give each person an immortal body on Judgment Day. Those who have the Spirit of Jesus will be allowed to live forever with God without any further problems caused by the sinful body and mind.
12 Worldly principles lead to certain doom because they displease God. God, however, will gladly accept anyone who has faith in Him and leaves the worldly principles behind. Therefore, we owe nothing to the world because we have been redeemed by God. Instead, we owe everything to God, and we should live by His principles in faith.
14 God adopts all those who follow Him.
15 A "fire and brimstone" sermon might scare someone away from the world, but that fear will be relieved once the person places his faith in God. When the believer follows God, he no longer sees God as the Judge, but as a loving father. The term "Abba" is similar to the childlike "daddy" in English.
16 Even if we do not feel like children of God at times, the Holy Spirit inside us will remind us that we are.
17 When a family adopts a child, the child gains the full rights of the natural children. According to Eastern tradition, when the head of the household died, the inheritance would be divided into equal portions among the male children. The oldest one would receive a "double portion," or twice as much as his other siblings.

In the spiritual realm there are a few parallels. Although we know that the Father will not die, His children still get to enjoy the benefits of the inheritance. Jesus is God's Son, and only "natural" heir. Since Jesus co-existed with God before Creation, He is the oldest (and only) Son. In faithfulness to the Father, Jesus carried out the plan of redemption and made the way for anyone who would believe to be adopted by God. As His children then, we also suffer like Jesus in that we are rejected by the world. However, Jesus will one day rule the world and expel what is evil. As believers, we have the hope that we will share in that glorious Kingdom.

31 God created the universe, and He will judge the world. Those who believe in Him are on His side. Who would dare oppose us? We know that the unbelieving world would dare, but we also know that such opposition is unwise.
32 We should not be anxious about God's provision. Jesus' sacrifice proves that God cares about us. Since He gave up His only Son for us, why would He not give us everything else He has promised?
33 There are two possible applications of this verse. First, if the world accuses us of wrong things because of our faith, we do not have to worry about that. They can accuse us of being narrow-minded and intolerant, but if they really look at the situation objectively, they will find the opposite is true.

Secondly, we know that Christians are not perfect. Even after salvation, we will occasionally sin as we continue to wrestle with the old, sinful nature. Today, the most common charge against Christians is hypocrisy. Christians say (correctly) that everyone should do things God's way, but are occasionally found to be guilty of sin. There is an unfortunate few whose mistakes do severe damage to their reputation. Despite this, the Christian can go to God and find forgiveness. The Christian can be encouraged and find the strength to overcome this sin. The world may never forgive him, but God will justify him.

The Church is composed of people who admit they are sinners and know that they must depend on God to save them. Such people are justified by God. Worldly people will condemn the smallest of sins in a Christian, but overlook their own glaring sins with glib excuses. However, in God's eyes there is only one thing that matters -- the relationship with Him. The Christian who has a long and deep relationship with God is far less likely to sin than a newer or "shallower" Christian. However, both are justified in God's eyes because of their relationship. The worldly person can do all kinds of "good things" and be a "good person," but in God's eyes, they are still guilty because they have neither asked for forgiveness nor been obedient to Him.

34 Some people are so opposed to Christianity that they would kill them if they had the chance. Some do succeed in persecuting and even killing Christians (e.g., in some countries it is a capital offense to be a Christian). However, the Christian knows that the final ruling will be made by God on Judgement Day. The whole world will then see that the Christians are justified and the world is condemned by God.
35 The Christian in this world might become discouraged because of the opposition around him. However, we must remember that nothing can separate us from Jesus' love. We may endure many hardships, but even in the midst of the worst times, Jesus' love is available to us. Furthermore, we have hope in the Day when we will know God's love unhindered by worldly interference.
36 This is from Psa 44:22 where the psalmists lament at being defeated even while they trust in God.
37 The world might see us as defeated, but we will ultimately have victory over the world through our faith in Jesus.
38 Death can not separate us from God because Jesus overcame death. Life can not separate us from God because we can pray to God no matter where we are. Angels (more specifically, fallen angels) actively try to keep us from God, but God is far more powerful than they are. No ruler of the earth has the ability to control our relationship with God. No force of nature is so powerful that God can not reach us through it. There well be no event, invention, or philosophy developed that is so compelling that it can prevent God from saving people or keep people from responding to God.
39 If we were to travel to the farthest reaches of space or dive to the lowest depths of the oceans, God could find us there. In short, God has created everything, and God has power over everything. Thus, there is nothing that can separate a believer from His love.

The only thing that can separate a person from God is his refusal to admit that he needs Jesus to save him.
