Teach the children how to pray

I was amazed by the verses that i read this morning Gen 21:15-17, Hagar lifted her voice and wept, but our God heard the voice of the lad (his son, Ishmael). Do you see the important of teaching how children to pray to our LORD Jesus Christ. Many of you may think that Ishmael is so young, how could he pray? but if you look at the subsequent verses that i have provided, Ishmael is over 13 years old. It is good to teach them how to pray when they are young, instead of saying:"papa or mummy will pray for you". Otherwise, they will grow up never know how to pray. Be Blessed!
Gen 16:16 Abram was eighty-six years old when Hagar bore Ishmael to Abram.
Gen 17:1 When Abram was ninety-nine years old, the LORD appeared to Abram and said to him, "I am Almighty God; walk before Me and be blameless.
Gen 17:19 Then God said: "No, Sarah your wife shall bear you a son, and you shall call his name Isaac; I will establish My covenant with him for an everlasting covenant, and with his descendants after him.

Gen 21:15-17
And the water in the skin was used up, and she (Hagar) placed the boy under one of the shrubs. Then she went and sat down across from him at a distance of about a bowshot; for she said to herself, "Let me not see the death of the boy." So she sat opposite him, and lifted her voice and wept. And God heard the voice of the lad. Then the angel of God called to Hagar out of heaven, and said to her, "What ails you, Hagar? Fear not, for God has heard the voice of the lad where he is.
