Prov. 3:5, 6 Trust in the Lord with all thine heart: and lean not to thine own understanding. In all thy ways acknowledge him, and he shall direct your paths.
As a human, and especially as a man, I am so often tempted to think that I can take care of myself, that I don't need someone else telling me what to do. I have to constantly remind myself that I am nothing outside of Christ, that I cannot do anything without God's strength. Obviously, outside of Christ's atonement and God's effectual calling I would be headed for hell, and rightly so. What's harder is keeping in mind the fact that I can do nothing physically outside of God and his mercy. It is a common misconception among men, that they are self made, or that they made themselves who they are today. When in fact it was God who gave them the strength of body to accomplish whatever feats they had to overcome in their lives. It is God who gives us the clarity of mind to make the daily decisions, that so often have lasting repercussions. That's not to mention the basic necessities he grants me such as the upkeep of my heartbeat and the air flowing through my lungs. How vain it is of me to imagine that there can be any physical success in this life outside of the mercies of God.
David's admonition was to trust in the lord with all thine heart, but instead we are tempted to trust God along with other things. A man who is sitting on a platform and yet has all sorts of safety belts on as well, is not truly trusting that platform to hold him up; people who claim to trust God for everything, and then go out and build up physical supports "just in case", are not trusting God with all their heart. I once heard of a man that said he honestly believed it was only through faith and trust in Jesus Christ that he could be saved, but just to be safe he also got baptized in the catholic church, took the Muslim pilgrimage to mecca, and did everything, every religion, told him was needed for salvation. That man was not trusting Jesus at all, but instead was just trusting in the Lord with some of his heart.
David also says that we need to acknowledge Him in all our ways. All too often we want to trust in God in some areas of our life, and yet unwilling to turn others over to him. We will trust him to give us each day the strength needed, but not believe he can do everything necessary to save us. Or, we will say that he can save us, but not keep us saved. Others trust God with their health, but not their money. David said it was expedient that we acknowledge God's sovereignty in every aspect of our lives.
The last part of these verses (like almost every other command in scripture) have a promise attached to the command. That if we do trust God with all our heart, in every aspect of our lives, he will direct your paths. God never leaves his children out to dry, David says in another psalm, that in all the years of his life he had never seen God's children begging bread. That's because God has promised that for those that do his will, he will lead them in the paths of righteousness for his names sake, and even in the valley of the shadow of death we need not fear evil for God is with us. Will you make the new years resolution with me, to try and trust God more in this next year? To acknowledge his omnipotence in every aspect of your life, and allow him to prove his faithfulness to keep his promise to direct our paths?
