Don Carson considers this question, ending with these reflections:
Still, we returned again and again to this pointed question: Granted that we ought to be engaged in acts of mercy, what safeguards can be set in place so as to minimize the risk that the deeds of mercy will finally swamp the proclamation of the gospel and the passionate desire to see men and women reconciled to God by faith in Christ Jesus and his atoning death and resurrection?Two stood out.
First, it is helpful to distinguish between the responsibilities of the church qua church and the responsibilities of Christians. Some writers flip back and forth between references to “Christians” and references to “church” as if there is no difference whatsoever. But many Christian thinkers, from Kuyperians to Baptists, have argued that if the church qua church is responsible for some of these substantial works of mercy, such works of mercy ought to come under the leaders of the church. It is very difficult to find any warrant for that step in the New Testament. Even before there were pastors/elders/overseers, the apostles themselves, according to Acts, recognized that they should not be diverted from the ministry of the Word and prayer, even by the inequities of food distribution among the faithful, so they saw to it that others were appointed to tackle the problem. Ministers of the gospel ought so to be teaching the Bible in all its comprehensiveness that they will be raising up believers with many different avenues of service, but they themselves must not become so embroiled in such multiplying ministries that their ministries of evangelism, Bible teaching, making disciples, instructing, baptizing, and the like, somehow get squeezed to the periphery and take on a purely formal veneer.
Second, one pastor astutely urged, “Preach hell.” Two things follow from this. (1) By adopting this priority we remind ourselves that as Christians we desire to relieve all suffering, from the temporal to the eternal. If we do not maintain such a panoramic vision, the relief of immediate suffering, as important as it is, may so command our focus that we fail to remind ourselves of Jesus’ rhetorical question, “What good will it be for you to gain the whole world yet forfeit your soul?” Read the closing lines of Revelation 14 and Revelation 20 when your vision becomes myopic. (2) As long as you are prepared to plead with men and women to be reconciled to God and to flee the coming wrath, you are preserving something that is central in the Bible, something that is intimately and irrefragably tied to the gospel itself—and those who want to shunt such themes aside and focus only on the relief of present suffering will not want to have much to do with you. Thus you will be free to preach and teach the whole counsel of God and to relieve all suffering, temporal and eternal, without being drawn into endless alliances in which people never focus on anything beyond threescore years and ten.
