All Christian belief must culminate in service or else the belief itself will wither away. Jesus said in His Sermon on the Mount, "Let your light so shine before men that they may see your good works and glorify your Father which is in heaven" (Matthew 5:16); again, in giving His parting instructions to His disciples, He commanded, "Go ye therefore and teach all nations" (Matthew 28:19,20). "Faith, if it hath not works, is dead" (James 2:17).
The New Testament rings with an optimistic trumpet call to service; there is not a single pessimistic note sounded. A man expresses his belief and he at once goes to work. To the fact that men were so willing to lead a strenuous Christian life in those early times is due in large measure the marvellous spread of the gospel faith.
The Object of the Call was not a cause but a Person (Acts 1:8; 2:22,36,38; 4:12; 10:43; 16:31); to set forth Jesus Christ as the Saviour of men. The world was full of evil. Society was corrupt. The state was bad. There were many giant wrongs crying out for the reformer. The apostles might have devoted themselves to the causes of social and political reform with splendid success. They might have bought only a gradual and purely friendly approach to the people whom they wished to influence, as we often do now, with some success, but the New Testament writings show that they believed that in the person of Jesus Christ they had a more powerful remedy for bad social and political conditions than any other which they could urge. In Christ they found a supreme object of service; for Him they were willing to give up houses, lands, position, even life itself (2 Timothy 4:6-8); for only through Him, they preached, could the world be truly reformed. Why then potter with temporary and minor remedies when the permanent and great remedy was at hand? Times have changed since the apostolic days, but for any lasting good in reform work Christ is still the great remedy. He must be at the centre of all social, political and temperance betterments or they are destined to fall short of the largest success.
The Place.—Where shall men serve the Christ?
1. In the heart; there is a goodness of conduct on the part of some men which has no relation to their heart's desire and is simply a cloak worn for appearance's sake. With this sort of goodness Jesus had no sympathy and denounced it as hypocrisy (Matthew 6:1-34; 23:27, 28). Christ's service must commence with an inward conformity to the law of God. This necessity for a new heart is very clearly brought out in His conversation with Nicodemus (John 3:1-21).
2. In the home. Jesus said to a man whom He had healed, "Go home to thy friends, and tell them how great things the Lord hath done for thee" (Mark 5:19). Anything that strengthens the home strengthens society and the state. Good homes are essential for the bringing up of children and the making of right characters. But it is in the home that the real testing often comes of a professed Christianity; if a Christian life can be lived and manifested here it is quite sure to stand the outward strain.
3. In the community. The disciples of Christ were commanded to begin their first service in Jerusalem (Acts 1:4,8), where Jesus had been the most persecuted and was finally crucified. It was no easy task for them to begin to preach Jesus, where they were the most looked down upon. But the command was justified when the day of Pentecost came with the marvellous moving power of the Holy Spirit (Acts 2). There can be no clearer teaching from this than that a Christian man should begin to serve Christ, testify for Him and work for Him in the community in which he resides no matter what the adverse conditions are. Here is the sanction for home missions.
4. Abroad. "Go ye into all the world and preach the gospel to every creature" (Mark 16:15; Matthew 28:18-20). The field of service broadens out from the heart until it takes in the whole world and every class and condition of men. Man under the guidance of Christ is led not only to think of saving himself, his home, his community, but all homes and communities however remote they may be from his own. Here is the sanction for foreign missions.
The urgency of the call is everywhere manifest in the New Testament. In the three years of His ministry Jesus Christ is incessant in His labours, calling upon men to turn to Him (Matthew 11:28-30). He urges watchfulness, prayerfulness, and earnestness in seeking to enter the kingdom of God (Matthew 11:12; 25:13; 26:41; Mark 14:38; Luke 11:9,10). Paul declared, "Woe is me, if I preach not the gospel" (1 Corinthians 9:16), and he urges Timothy to "preach the word" and to be "instant in season and out of season" (2 Timothy 4:1,2).
A conflict is going on in the world and those who believe in Christ are besought to take every possible opportunity and every means to advance His gospel and cause men to accept Him as their Saviour (Ephesians 6:10-18).
