“Unless you are converted and become as little children, you will by no means enter the kingdom of heaven.” MATTHEW 18:3
The first step towards entering into the kingdom of grace is to become as little children—lowly in heart, knowing yourselves utterly ignorant and helpless, and hanging wholly on your Father in heaven for a supply of all your wants. It is further true that unless you are turned from darkness to light, from the power of Satan to God, except you are entirely, inwardly changed, renewed in the image of God, you cannot enter into the kingdom of glory. Thus must everyone be converted in this life, or he can never enter into life eternal. All who are in this sense little children are unspeakably dear to our Lord. Therefore, help them all you can, as if it were Christ Himself in person. And see that you do not offend them, Jesus said (v. 6), or turn them out of the right way; neither hinder them in it. Let us be careful, then, to receive and not to offend the very weakest believer in Christ. For as inconsiderable as some of these may appear to us, the very angels of God have a peculiar charge over them (v. 10). Indeed, these angels are of the highest order, who continually behold the face of the Father, continually appear at the throne of the Most High. And these “little children” are the very ones Christ came to save.
