UNDERSTANDING THE PLAN

"The Lord your God will make you abound in all the work of your hand, in the fruit of your body, in the increase of your livestock, and in the produce of your land for good... if you obey the voice of the Lord your God, to keep His commandments and His statutes which are written in this Book of the Law, and if you turn to the Lord your God with all your heart and with all your soul."Deuteronomy 30.9-10

All Divine promises depend on listening to the Voice of God. 
The Voice of God is the voice of rational faith. This kind of faith comes from the obedience and practice of His Word.
This is the requirement for the fulfillment of His promises.

BLESSED INHERITANCE

"The God of my father was my help and delivered me from the sword of Pharaoh."Exodus 18.4

Abraham was obedient and faithful to the Lord. 
His son, Isaac inherited the same quality of faith. And when he found himself before Pharaoh, he called out to his father's God and was delivered.
When they are wise, parents follow the same example. They give priority to the Christian faith of the Bible to educate their children. This will guarantee protection and success.
