Matthew 18:4 Therefore whoever humbles himself as this little child is the greatest in the kingdom of heaven.
When we are young babes without much of a care in the world, we are very trusting and follow those who try to tell us where we go. If we do have good parents and guardians then we grow up to know what is good and right.
God wants us to be in that sort of position toward Him so that we accept the truth and righteousness and trust in it, growing up in it as being the core of our lives.
When we take on God’s ways and live by them, we grow to be much stronger Christians who can help and support others in their walk toward God as well.
