Motive is "that within the individual, rather than without, which incites him to action." Peter's sermon on Pentecost made the hearers aware of circumstances which produced self-judgment--- "we have killed the long awaited Messiah. What shall we do?" Under these conditions the answer can be brief and to the point. There was no need for charts, diagrams, and argumentative sermons on baptism.
This is no indictment of defense and proclamation of doctrinal details. Where such differences exist, and are the deferment to full obedience, they must be thrashed out. But in many cases if we would expend greater efforts to convince men of their true status before a righteously indignant God, we would not have to press so fruitlessly the details of His will. A man who realizes he is drowning does not argue about the color of the life buoy thrown to him.
We strive for men's hearts: casting down man's evil reasonings, his pride, and bringing into captivity his thoughts to the obedience of Christ, (2 Cor. 10:4 (For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strongholds;) 5. Casting down imaginations and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ. If we are more interested in winning an argument than in saving a soul, we will certainly fail in the latter, and probably in the former. We are trying to win a man, not whip him.
To change the attitude of others, so that they will be open and receptive to the gospel of Christ, we may first have to revise our attitude. We must somehow become one with the Lord Jesus, who loved and sacrificed Himself for mankind; not because we were lovely, but "while we were sinners."
