Psalms 103

1 God is good, and we can honor Him with everything within us: our thoughts, our creativity, our songs, etc.
2 If we need reminders of God's goodness, we need only list what He has done for us.
3 God will forgive the sins of those who ask Him. The psalmist would not have known about Jesus the way that we do today, but he would have believed God's promise of the coming Messiah that would take away sins this way.

Besides healing our spirits, God can heal our bodies, too. Sometimes God intervenes miraculously to heal a disease. However, we also know that God will give us all new bodies on the Last Day that will be completely free from and resistant to all ailments.

4 This does not merely refer to saving a person from destruction in battle or other life difficulties. It refers to saving a person from eternal destruction. God will extend His loving kindness and mercy on earth, but the believer will wear these things for all eternity.
5 God provides for our daily needs. For most people this means working with the talents God has given them to grow or earn food. For some, this means He provides through the generosity of others.
6 Though people are oppressed in this world, God will see that justice is served. Sometimes justice is served during this lifetime, but others will have to wait until Judgement Day for all things to be made right.
7 God gave His Law to Israel so they would know what His righteousness and justice demanded. The Israelites saw God's judgement against the Egyptians and the wicked Canaanites that once inhabited the Promised Land.
8 Since all people are tainted by sin, offending God comes "naturally" to us. God does not want to be angry with us. He not only shows incredible patience with us, but He demonstrated His great mercy towards us by placing our deserved punishment on His Son, Jesus. Only when we refuse to find forgiveness through Jesus does God's patience end.
9 A righteous person may sin and God may punish him for it, but God's anger will eventually be satisfied, and the offender will be restored to His good favor.
10 Sin is punishable by death, that is, eternal separation from God and His goodness. Every person is deserving of the death penalty. However, God sent Jesus to pay for our sins. When we believe in Him, He suffers this penalty for us.
11 God's mercy towards people of faith is immeasurable.
12 We do not know if David knew that on a globe one could travel east or west indefinitely (or if that was God's intention). Regardless, the point is clear that when we trust in God, He removes our transgressions from us. David, of course, did not know of Jesus, but he knew that God promised a Messiah. It is this faith that was David's salvation.
13 Parents are always saddened when their children do wrong, and will do whatever they can to help them. When we trust God, we become like adopted children, and He cares for us greatly.
14 We are weak both spiritually and physically compared to Him. Our bodies are also mortal. God remembers these things, and this helps Him to be patient with us.
15 Many plants are seasonal. In the spring many plants spring up and display wonderful flowers. Soon, however, the flowers fade, and the leaves wither away before the summer. In God's perspective, the lifetime of a person is similar. We live and flourish for several years, but then our bodies wear out and die.
17 Nevertheless, God can still have mercy on us, because we will one day be resurrected.
18 Those who have accepted God's promised plan for salvation will forever live in His care.
