Have you ever refrained from partaking in the Lord’s Supper because you didn’t feel worthy? Or maybe because you struggled with a lack of assurance? If so, look at question #172 from the Larger Catechism:
“Q. 172. May one who doubts of his being in Christ, or of his due preparation, come to the Lord’s supper?
A. One who doubts of his being in Christ, or of his due preparation to the sacrament of the Lord’s supper, may have true interest in Christ, though he be not yet assured thereof; and in God’s account has it, if he is duly affected with the apprehension of the want of it, and unfeignedly desires to be found in Christ, and to depart from iniquity: in which case (because promises are made, and this sacrament is appointed, for the relief even of weak and doubting Christians) he is to bewail his unbelief, and labor to have his doubts resolved; and, so doing, he may and ought to come to the Lord’s supper, that he may be further strengthened.” (The Westminster Larger Catechism)
In other words, there is a huge difference between weak faith and not having faith at all. And the sacrament is for strengthening our faith! If you think that your faith or assurance is lacking, but you sincerely desire for that to change, then the table is for you!
If you struggle with sin, that does not disqualify you from the Lord’s Table. (If that were the case, what honest sincere believer could ever take it?) The bread and the cup are meant to strengthen you in the grace of Christ. There is all the difference in the world between someone who is hardened in unrepentant sin and a believer who feels the weight of the same struggle that the Apostle Paul himself confessed in Romans chapter 7.
So the Lord’s Table is for weak people like you and me.
If you are not a believer in Jesus Christ, then by all means abstain from partaking on Sunday – let the bread and the cup pass by.
But if that is the case, turn to the One whose death is proclaimed by the bread and cup. Trust in Christ alone for salvation! And then next time around, you can partake with the Lord’s people in the Sacrament of the Lord’s Supper.
