Psalm 139:5…”You hem me in behind and before, and you lay your hand upon me.” As though we were caught in an ambush, or threatened by an army which has us completely boxed in, we are surrounded by the Lord. God has set us where we are and protects our every move. Behind us there is God recording our sins, or in grace (through repentance and faith in Christ) blotting out the remembrance of them. Before us there is God foreknowing all our deeds, and providing for all our wants. We cannot turn back and escape him, for he is behind, and we cannot go forward and outmarch him, for he is before. This should bring the believer great comfort, but is terrifying to those outside of Christ. He is perfectly holy and perfectly just, and we all desperately need the blood of His perfect Son to be sprinkled on us in order to avoid His perfect wrath. He knows and hates our sins, but has in Christ graciously provided a rescue plan from His own wrath.
Psalm 139:4…”Before a word is on my tongue you, Lord, know it completely.” The words we use matter, because God knows all of them. In fact, he knows what we’ll say before we speak. This verse is an amazing reflection on God’s sovereignty. We cannot fathom this kind of omniscience, so we need to not doubt this attribute of God, even if we don’t fully understand. Admitting that there is knowledge and truth outside of our own limited minds is an important step in believing the authority of scripture. Much doubt comes from our pride in thinking that something can only be true if we fully comprehend it. Absolute truth exists regardless of our opinions. When we doubt the authority of scripture, we misunderstand what God is like, which limits our spiritual growth.
Psalm 139:1…”You have searched me, Lord, and you know me.” God has perfect knowledge of us, and is aware of all our thoughts and actions before they even occur. It is more profitable to meditate on Divine truths, applying them to our own lives, and with hearts lifted to God in prayer, than with a curious or disputing frame of mind. God knows all things being omniscient, and is everywhere, being omnipresent. These are truths acknowledged by many believers, yet they are seldom applied to our lives practically. How much more content would we be if we habitually believed God was this big? His knowledge is infinite, and He knows us better than we know ourselves.
