Occasionally, God has to remind us that He is mighty and true. He keeps His promises and has blessed us for generations. In this case, the one to whom God speaks is the patriarch, Isaac, son of Abraham.
God reminds Isaac that He has blessed Abraham, and that He will continue to bless their family.
Isaac likely remembered when God sent a ram to serve as sacrifice in his place. He probably remembered that God had delivered their family from war and famine. God had helped them prosper. Their family would some day be as numerous as the stars.
That God, the God of Abraham, Isaac, and Jacob is our God. He’s the God of our fathers. He is unchanging, eternal, loving, merciful, and no respecter of persons. The same God who blessed Abraham, parted the Red Sea for Moses, delivered Daniel from the lion’s den, and raised Christ from the grave… That same God dwells in your heart.
Do not fear, the God of Abraham is with you.
