Your question depends on many points in the state of the soul. The first question would be—have you ever got settled assurance of conscience before God so that that should be true of you which is said, "The worshippers once purged should have no more conscience of sins"? When we have not this, every fault mixes itself up with the question of the light in which God views us, and the question is not restoration, but recovering some sense of standing before God, which is a very different one. God is not really known in love, though we may believe generally that He is so since He has visited us in mercy. If I am not out of Egypt, that is, if I have not a clear knowledge of God as a redeeming God, and I am looking to God who defends me against His judgment by blood, my thought of Him is yet wholly imperfect, my failures give fears, not pain properly, to my spirit. The great point is then to know and believe that He has redeemed us in love, and taken us in the resurrection of Christ out of the whole state and condition I was in before; that He justifies me, not that I am justified before Him—and both are right, but the former only is liberty. When this is fully known love is never doubted, but we are brought to feel it is grieved; but it is therefore still known to be there; and hence, when the heart really looks to Him it is soon restored, though the Lord may keep it so long in suspense, as to communion, as may be necessary to probe the heart as much as needed. If you have the full assurance that God is love to you at all times, the witness of His Spirit in communion will soon be restored to you.
But there is another question. When I have not a positive sin on my conscience, I cannot properly excommunicate myself. Hence, the separating myself (as to profession outwardly, of course, I mean) from the unity of the body of Christ, of which the Lord's supper is the sign, is a very serious thing; and we are not justified in doing it except on very positive ground. If I felt there had been serious neglect of God, and He was positively dealing with me seriously about my sin, I should rather stay away, but it is a very serious thing when once one sees that it is the unity of Christ's body; but then one ought to take up the matter very seriously indeed with one's self. In many, the abstaining from communion is much too light a matter. On the other hand, if it be as is the case in some souls, only a distrust of God's love, of which the enemy is taking advantage, abstaining from it would only increase the uncertainty of soul. The word of scripture is not, Let a man examine himself, whether he should eat, but, "Let a man examine himself, and so let him eat." This is the general rule; not to do it lightly—but, in judging evil, to do it. If the peace I first spoke of is not possessed, we cannot judge rightly, because restoring love is not known. The first great question for you is, Do you know really the love of God in an assured conscience (not merely attracted heart)? If so, I should say, go—but do it seriously, so as not to trifle with any evil—unless some definite dealing of God with you about evil be in hand, then you would do well to refrain till that be settled. I know not whether speaking thus generally (I could only do this, of course) will be of any avail. Look to the Lord; He will guide the meek in judgment, and such as are humble them will He teach His way; and trust His love, only truly judge yourself. If I can be of any further use I shall be happy.
Very truly yours in Christ.
The table is the place of full communion; but it is a different thing to stay away voluntarily, when one is there, and to hesitate in going at first. Seek whether you have ever had your conscience fully at peace with God, and then, daily power for communion, which is surely in Christ for you when walking in the way of God's will.
