"And they brought young children to Him, that He should touch them: and His disciples rebuked those that brought them. But when Jesus saw it, He was much displeased, and said unto them, Suffer the little children to come unto me, and forbid them not: for of such is the kingdom of God. Verily I say unto you, Whosoever shall not receive the kingdom of God as a little child, he shall not enter therein." (Mark 10:13-15)
The above verses, though short, give us so much in terms of what Jesus was trying to teach when He was on Earth. The final remark says it all, that we must become as little children in order to enter into His kingdom. Basically, we need to love like them, rely upon our Heavenly Father like they rely on their parents, and have faith like them.
I have been made a very proud father as I have witnessed the faith my son has in the power of prayer. He’ll be 6 in mid-July, and he’s seen the power of God in his young life multiple times, and he is quick to ask me to pray with him or for him.
