Assuredly, I say to you, whoever does not receive the kingdom of God as a little child will by no means enter it. (Mark 10:15)
There is freshness in children. They are full of life and the anticipation it brings. Children laugh, and do not fret about the things over which they have no control. The tendency of a child is to trust and believe. Thus they are wonderful recipients of faith. A young child has unconditional faith in his or her parents. Their world is not complicated by sin or doubts. They dream dreams and expect them to come true.
Children are moldable. They can be trained to obey the truth and reject a lie. This is to be the character by which we come to Christ; not just for the first time, but every time. We are to be loving, obedient children, full of faith and joy. We are to unconditionally trust our Heavenly Father. Unfortunately, we are usually childish in our actions, rather than being childlike.
