The Bible consistently identifies the Lord as a jealous God. As the Creator, He deserves man’s undivided allegiance. As the most High God, He is worthy of man’s unadulterated worship. It is often in this vein that the Bible speaks of God’s jealousy. He warned Israel not to make or bow down to any graven images (Exodus 20:4-5; Deuteronomy 5:8-9; Psalm 78:58) because He was a jealous God and would have no choice but to judge such infidelity. The same was true of any false god (Deuteronomy 32:16) or sin (1 Kings 14:22) which man allowed to come between him and his Creator. God is perfectly just in His jealousy since man was created for God’s pleasure (Revelation 4:11).
In order to be saved, a person must place his faith solely upon Christ’s death, burial, and resurrection for the means of salvation. Paul defined this central body of truth as the gospel of the grace of God (1 Corinthians 15:1-4; Acts 20:24). Though believers may tell what the Lord has done in their lives since being saved, the most important truth when witnessing involves Christ’s crucifixion, death, and resurrection from the dead. This truth, the resurrection of the Lord Jesus, became the theme of the early church. A careful study of the evangelistic messages of the early church testifies to this fact. Just as this doctrine historically served as the central truth when dealing with the lost, it should continue to be so today.
