#40 Part 21 The Promise of Eternal Life is Also of Sheer Grace.If, then, the promise of the land of Canaan is a pure promise of grace, how much more will not the promise of eternal life be a pure promise of grace, which flows forth simply and solely out of the undeserved grace of God, and in no way depends on the merits of one’s own works? When you have done everything that I have commanded, then still say, we are non-beneficial servants; we have done what we were obligated to do. That’s how Jesus teaches us in Luke 17:10: With what would we be able to earn the promise of eternal life? If someone does a particular thing, but does not actually perfectly fulfill what he already owes, he cannot earn anything with his works.
Now, however, we humans have this privilege: that all the things we do to glorify God and do to please Him, we are to do since we already owe Him that jure creationis, conservationis & redemptionis because He has created, preserved, and redeemed us; indeed, we do not do this perfectly on account of the fact that in this life, we do not perfectly do all these things; how, then, would we be able to earn anything from God the Lord with our indebted imperfection? Oh! The poor cannot earn it! Yet we as poor beggars have to petition and beg before God’s door for daily bread (Mat. 6:11). How dare we ever more deeply fall into this line of thinking that we might be able earn heaven and eternal life from God the Lord by our good works? The holy apostle says it well in Rom. 8:18—I maintain that the sufferings in these times is not worth compare to the glory which shall be revealed to us. If the sufferings of this present time are not worth comparing to eternal glory, then suffering for the sake of God’s glory is of much weightier and greater importance than works. And in Rom. 6:23: Eternal life is (not a payment or an earned wage from good works, but a gift of God χάρισμα, a gift of grace) in Christ Jesus our Lord, which He, through His precious merit and perfect obedience, won for us. … What God the Lord has promised us, He gives to us on the grounds of grace, not as a reward for our works.
