If when you come to the altar, there you remember that your brother has anything against you, not — If you rake up something by a morbid sensitiveness, but — “If thou…rememberest,” that is, if it is brought to your conscious mind by the Spirit of God: “first be reconciled to thy brother, and then come and offer thy gift.” Never object to the intense sensitiveness of the Spirit of God in you when He is educating you down to the scruple.
“First be reconciled to thy brother…” Our Lord’s direction is simple — “first be reconciled.” Go back the way you came, go the way indicated to you by the conviction given at the altar; have an attitude of mind and a temper of soul to the one who has something against you that makes reconciliation as natural as breathing. Jesus does not mention the other person, He says — you go. There is no question of your rights. The stamp of the saint is that he can waive his own rights and obey the Lord Jesus.
“And then come and offer thy gift.” The process is clearly marked. First, the heroic spirit of self-sacrifice, then the sudden checking by the sensitiveness of the Holy Spirit, and the stoppage at the point of conviction; then the way of obedience to the word of God, constructing an unblameable attitude of mind and temper to the one with whom you have been in the wrong; then the glad, simple, unhindered offering of your gift to God.
