Matthew 18:3 or Mark 10:15 seems like the verses people think of. One way to have faith like a child, but not the naivete' would be to study the Word of God.

Amen! To what has been said...
Fair use for education and discussion purposes:

"Childlike Faith is the wonder and awe at what Christ did for us. It is a synergy of trust, hope, and unpretentiousness that knows the Lord loves us and will lead us. Because of our trust in the Lord, we are more able to take comfort in Him. Childlike faith sees the world as exciting and adventurous, and worth pursuing with our faith so opportunities to please God override our complacency and the attitude of “been there, done that,” even though we may have. It is a part of us that we should never lose. It enables us to maintain our humbleness and enthusiasm and not become just a subculture or routine! We are not to act like children towards others, but our faith and example must be authentic (Psalm 23; 131; Matt. 18:2-4; 34; John 10:1-18; 1 Cor. 1:22-30; James 2:14-19; Heb. 11:1). "

This verse has been a good example for me.

So Jesus answered them by saying, I assure you, most solemnly I tell you, the Son is able to do nothing of Himself (of His own accord); but He is able to do only what He sees the Father doing, for whatever the Father does is what the Son does in the same way [in His turn]. John 5:19

And- But the Comforter (Counselor, Helper, Intercessor, Advocate, Strengthener, Standby), the Holy Spirit, Whom the Father will send in My name [in My place, to represent Me and act on My behalf], He will teach you all things. And He will cause you to recall (will remind you of, bring to your remembrance) everything I have told you. John 14:26

Great Topic... God Bless~

I've always taken it to mean what a little kid does, rather than what they might believe out of naivete.

They're friends with anyone and everyone. They don't even need to know your name and they're playing with you. Issues like race, enemies from different countries, other adult prejudices haven't entered their hearts yet.

They fully trust what their parents tell them. Christ didn't mean to trust even when you're lied to, so the parallel would be to trust our Father.

They have no concept of danger. They're not ashamed. They find wonder in mundane things -- they OO and AAH at everything. "Daddy, Daddy, look at the big fishy!" No cynicism yet of "Yeah, yeah, that's really...great, son."

There's no worry about tomorrow. No stress about bills. No fright about where dinner is coming from because Daddy always makes sure it's on the table.

They hold their parents' hand and don't even look where they're going, trusting Daddy knows the way.

And whenever they ARE frightened/hurt/upset/ they run straight into their Daddys' arms.

That is childlike faith.
