God is full of grace. From His fulness He overflows in good things to the undeserving. He gives many good, undeserved things to those who hate Him. Jesus said that His Father makes His sun rise on the evil and sends rain on the unjust. We call this common grace. Do you have food? Do you have sight? Do you have kids? These are all blessings that believers and unbelievers can know.
Christians know another sort of grace, a special grace, a grace not given to everyone. We call it particular grace. God gives it particularly to His elect, those for whom His Son died. Particular grace is exceptional, exclusive, reserved for His people alone.
Does this make us special? Yes. Does this mean we deserved grace? No, not in a million years, no. If grace were earned it wouldn’t be grace.
Consider what the Lord revealed through Jeremiah.
Thus says the LORD: “Let not the wise man boast in his wisdom, let not the mighty man boast in his might, let not the rich man boast in his riches, but let him who boasts boast in this, that he understands and knows me, that I am the LORD who practices steadfast love, justice, and righteousness in the earth.” (Jeremiah 9:23–24, ESV)
We don’t honor God by claiming that we deserve His blessings. We also don’t honor God by claiming that we don’t have special, particular blessings that others don’t. It is all about boasting. Everyone boasts. Many boast in self. Some boast that they prohibit boasting, which is a backward way of self-boasting. And those who know particular grace boast in Christ.
This meal of communing is a meal of particular grace. Bread is for men, but the body of Christ is for believers only. Wine is for celebration, but the cup of Christ’s blood belongs only to the people who celebrate a bloody sacrifice on the cross.
Every week we boast in something exclusive. The Lord’s Table is reserved for particular people who received particular grace. If you don’t know Christ, you are invited to Christ but not to this meal. If you do know Christ, this meal invites you to everything in Christ.
