To “become like little children” in the Gospel reading does not mean to be ignorant and weak, helpless and gullible. To “become like little children” means to be little children totally dependent on their parents and elders in our relationship with our heavenly Father. It means we should be “innocent,” with the pure innocence of little children, trusting, obedient and dependent on our Father in heaven in the way of little children with their parents. It means we somehow let go of our pride, arrogance and complete confidence in ourselves.
In the first reading Yahweh, God of Israel, faithful to his covenant, reiterates his love for Israel and promises their return to Jerusalem, “I am going to save my people … They will be my people and I shall be their God.”
Are we able to “become like little children” before our heavenly Father? Are we able to have complete trust and confidence that our heavenly Father will take care of us? “If God so clothes the grass in the field which blooms today and is to be burned tomorrow in an oven, how much more will he clothe you?” (Mt 6: 30) “As bad as you are, you know how to give good things to your children. How much more, then, will your Father in heaven give good things to those who ask him!” (Mt 7: 11)
