The Lord's Supper is a time to Remember what Christ has done for believers.
Come to this sacred table, not because you must, but because you may.
Come to testify not that you are righteous, but that you sincerely love Christ, and desire to be His true disciple.
Come not because you are strong, but because you are weak and frail.
Come not because you have any claim on heaven's rewards, but because in your frailty and sin you stand in constant need of heaven's mercy and grace.
Come not to express an opinion, but to seek His presence and pray to walk in His Spirit.
Come just as you are.
