Being childlike is a prerequisite for My Kingdom because that is what faith requires. Faith is the substance of things hoped for. As a child, you come to expect certain things from your father or mother. You do not worry if things will be done for you; you just expect it. That is faith. Unfortunately, as you grew older, and promises were broken, you became disillusioned. You learned that others were not always trustworthy.
When a parent fails to keep a promise it lodges as a deep betrayal in a child’s heart. As an adult, you must release those that have failed you. Even then, if I want you to have or do something, I can always make a way. I am the one who provides water in the wilderness. Put your hope and trust in Me. I am a good Father. I always have your best interests at heart. Return to childlike faith once again. Rejoice always. Pray always. Give thanks always. Everything is going to be OK. In the end, My purposes will stand.
Matthew 18:2-4 Amplified Bible (AMP)
2 He called a little child and set him before them, 3 and said, “I assure you and most solemnly say to you, unless you repent [that is, change your inner self—your old way of thinking, live changed lives] and become like children [trusting, humble, and forgiving], you will never enter the kingdom of heaven. 4 Therefore, whoever humbles himself like this child is greatest in the kingdom of heaven.
