68. Christ Jesus always manifested his preferential love for the little ones (cf. Mk 10:13-16). The Gospel itself is deeply permeated by the truth about children. What, indeed, is meant by these words: “unless you turn and become like children, you will never enter the kingdom of heaven” (Mt 18:3)? Does not Jesus make the child a model, even for adults? The child has something which must never be lacking in those who would enter the kingdom of heaven. Heaven is promised to all who are simple, like children, to all who, like them, are filled with a spirit of trusting abandonment, pure and rich in goodness. They alone can find in God a Father and become, through Jesus, children of God. Sons and daughters of our parents, God wants us all to become his adopted children by grace!
