Children are not afraid to profess what they know even if they were wrong. They have courage to shout it loud, then I see one of the reasons why Jesus said if anyone of you will not receive the kingdom of God like the children he will not enter it.
Can you publicly confess Jesus? Remember, He said "if any one deny me publicly I will deny him in front of my Father and the Angels".

We came to this world with an empty brain, it is when we get to the world that we acquire knowledge to fill it.
Some we acquired by impartation, be it self-impartation or by an external force, some we pay for to acquire, some we acquire through thinking and meditation.
But you know that the best knowledge you can acquire is the knowledge from the WORD OF GOD.
With His WORD, we cannot stumble because it will light our path. (Psalms 119:105).
