This meal is a meal of all grace. When we shrink back from it, we do so (most often) because of our sins. But because it is a meal of grace, all the arguments we might construct out of our sins do not and cannot work.
This is because grace is there because of our sins, it presupposes them. Just as a bath presupposes someone in need of a bath, so also the blood of Jesus Christ here presented is the blood that cleanses us from all unrighteousness. The body of Jesus Christ here presented is the body that was broken on account of all unrighteousness. What argument fashioned from sins can you bring to this Table that is not quickly, thoroughly, and wonderfully refuted?
There is a convoluted way to turn a table of grace into a table of judgment, and some have done it, but they have only succeeded in doing it by ignoring almost everything that is said about it. Some have gotten sick and died because of how they approached the cup of blessing, but their mistake was not a minor one, and their rebellion was not a subtlety.
We are convinced of better things concerning you. You cannot argue from your sins and shrink back, and you cannot argue from the magnitude of your sins and shrink back, because this Table is set with grace enough for the world. Neither can you argue from the secret decrees of God—because you don’t know them. God does know His decrees, and He has authorized His ministers to summon you to come.
This is why, at the end of the day, the only reason people do not come to Christ is because of they sin they are committing at that very moment. They are refusing to repent. They are refusing to bow down. They are refusing to be a supplicant.
But you are not so. Come, and welcome, to Jesus Christ.
