One of the great dangers confronting those who would give themselves to mercy ministry is that of forgetting the antithesis. Biblical wisdom always remembers the antithesis, and places it where God has placed it. Forgetting the antithesis frequently consists of selecting a biblical virtue, absolutizing it, and using it to contradict or “balance” other biblical virtues. This is the basic (and very serious) error of the pacifist. The problem is not what he affirms so much, but rather what he denies.
Righteous peace is a glorious thing (Is. 11:9) but must never be set in opposition to righteous war, because God Himself is the Warrior, training us in the arts of war (Ps. 144:1). Who is it that does this? He is the Prince of Peace (Is. 9:6). Unity is a glorious thing (Ps. 133:1), but must never be set against righteous confrontation and rebuke, and separation if necessary. This is why it is not a contradiction to divide from a divisive man (Rom. 16:17).
When someone finds a hammer, everything looks like a nail. When someone first discovers how much the Bible extols and urges mercy (as it most certainly does), it is easy to forget the virtue that can be found in showing no mercy. God is the one who shows mercy to a thousand generations (Num 14:18; Dt. 7:9). God is also the one who refuses to show mercy (Is. 9:17; 27:11; Hos. 1:6). The believing response to such apparent tensions is to accept it all at face value, and let God sort it out. The unbelieving response is to privilege one set of verses over the other, and, as time goes by, to forget about the neglected set of verses entirely.
But the fact is plain enough. Consider the fierce prophecy concerning Judas, and look closely at the reason for the judgment.
Lest anyone think that this is “an Old Testament” thing, remember that Judas did his pilfering in the very presence of the Lord Jesus. And we should also remember what Jesus promises us — blessed are the merciful for they shall obtain mercy (Matt. 5:7). And the Lord’s brother puts it this way:
So unless this framework is settled in the bones of mercy ministers, the work they do will descend over time into a sink of sentimentalism. The foundations of mercy are found at the mercy seat, and the blood that was sprinkled there was for the sheep, and not for the goats. And the doctrine of the final judgment, violent as it is, is the other great touchstone. This is why, when you are checking out a charitable Christian ministry, two of the more important questions you might ask will be, first, “What is your view of the vicarious and substitutionary atonement of Christ?” and second, “What is your doctrine of the last judgment?” If the answers given are robust and orthodox, then you at least have the foundation in place for real mercy work.
