Like a Child

At that time the disciples came to Jesus and asked, “Who is greatest in the kingdom of heaven?” He called a little child and set him before them, 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.

Children are precious and adorable. They come to us blank and what we pour into them is what they become. You can take a newly born baby and transfer them to a different nation and culture from which they were born in and as they grow up you will never be able to know that they were born in a different culture because they will adapt to the ways and culture of the place they grow up in.
When we come to Jesus we are born again and we have to repent, change our way of thinking, be ready to allow our life to be influenced in a new different way of thinking. Like a child we have to empty ourselves and all we have known and allow Christ to pour into us.
Children are trusting. We should have the same trust element when interacting with God.

Trust in and rely confidently on the Lord with all your heart And do not rely on your own insight or understanding. In all your ways know and acknowledge and recognize Him, And He will make your paths straight and smooth [removing obstacles that block your way].

Children believe and trust what they are told. They do not try to figure out how it will all work out and come together. If you tell a child you will buy them a plane, they will not look at your pay slip and worry about how you will do it. They will get excited and tell all their friends the good news and they will keep reminding you of your promise because they trust what you say because they believe you love them.
How much more God the good good father?

God has many promises for you and I in the bible, do we believe them get excited and tell our friends about it or do we doubt and worry because in the natural we can’t figure out how it will all work out?
Become like a child.
