It pays to be a little child. In fact, Jesus Himself said, "Suffer the little children to come unto Me, for of such is the Kingdom of Heaven." (Mk.10:14) We're to be like little children, loving, sweet, simple believers.--In childlike faith, believing and receiving all that the Lord has for us!
Children are samples of the citizenry of Heaven!--Like little angels dropped from the sky! They're so fresh from Heaven, they understand and are not the least bit fearful when it comes to the things of the Lord and the Spirit and even spiritual experiences. It is given to children to be rich in faith! Faith just comes natural to them. They are so fresh from Heavenly places that they have faith to believe anything God says, and with them nothing is impossible!
The problem with many grown-ups is that they know too much!--They've been educated out of their childlike faith! But there are others of trusting childlike faith who are daily doing things that doubting intellectuals say can't be done! So be like a little child and anything wonderful can happen!
