But, how can you trust God if you do not know Him?
When you read the word of God, you learn about the character of God (His likes and His dislikes). You learn about the behavior that is pleasing to God. You learn how God delights in giving His children the desires of their hearts. You learn that He will not abandon his people even when they make mistakes. You learn how to identify the people of God in a fallen world. You learn about the miracles of God that occur even now.
And GUESS WHAT? Over time, you learn how good God is. The more time you spend talking to God and learning of God, the more you realize that God only does good things. And then you start gradually relying on God more and more. First you assign God small tasks, e.g., assistance paying bills, healing for a friend, a path forward at work. Soon you learn to pray more and more effectively and then you start to see God move on the things you have entrusted to Him (not always in the way you want but always in a good way). Now, you start to relax. You are now eager to abandon your strategies for success opting to let this Awesome GOD take the lead.
And darling, at that moment (the moment you move over to the passenger seat), you will be AMAZED at what God Power will do for you and for those you entrust to Him.
