The first lesson a baby learns in life is to trust. The bond between a mother and the infant is trust. The baby learns to trust the mother to be there. The cry is heard and mother's loving arms lift the infant for nurture and care. Likewise, we can trust God, if we are born again.
We trust God and lean not on our own understanding. The Bible says, "Trust in the LORD with all your heart, and lean not on your own understanding"(Proverbs 3:5). None of us can understand all about the greatness of God. Our understanding is limited. Like an infant who does not understand the mother, yet trust is developed. There is so much that we don't understand about God. Therefore, we trust God and lean not on our own understanding.
We trust God believing the promises of the Bible. Trusting God is believing his promises according to Holy Scripture. He is faithful to all his promises in the Bible. Our bond with God is based upon his word of promise found in the Bible. If we trust God, we are trusting the promises of his word.
We trust God living by the promises in the Bible. Read the promises of God. Pray the promises of God. We trust God to always keep his word of promise in our lives. We trust God when we understand and when we don't. We trust God by depending upon his word.
