In case you’re not convinced of the comprehensiveness of God’s forgiveness, Paul writes, “According to the riches of his grace, which he lavished upon us” (Eph 1:7-8). You’ll notice he uses this language of certainty and totality. God has blessed us in Christ with every spiritual blessing, not some spiritual blessings (Eph 1:3). The riches of his grace have been lavished upon us. And he doesn’t speak of the mere possibility of redemption, but the absolute certainty of it.
We never need to worry that God’s grace isn’t enough. The Bible says, “Where sin increased, grace abounded all the more” (Ro 5:20). Again, his forgiveness is infinite. The word lavished signifies that God’s generosity is more than a small favor or act of kindness. Rather, he is extravagant in the blessings he gives. His generosity is over the top if you will.
Paul says that God forgives according to the riches of his grace (Eph 1:7). Let’s say that Bill Gates gives fifty dollars to charity. Is he giving according to his riches? Not really. Bill Gates’ net worth is more than eighty billion dollars. He would need to give at least several thousands before he would come anywhere close to giving according to his riches. Anything less would be him giving out of his riches. Perhaps we could say that he is giving from his riches. For Bill Gates to give according to his riches would require an amount that is much closer to his net worth.
As for God, he gives according to the riches of his grace (Eph 1:7). How much is that? You tell me. How much is your son worth?
