A witness is one who testifies to the certainty of an event. As such, the apostles gave witness to the resurrection of the Lord Jesus Christ. By doing so, they were declaring the resurrection to be an absolute truth. The disciples physically witnessed the fact that the Lord Jesus Christ had been put to death, but was alive and well. Although no believer today physically saw the birth, life, death, burial, or resurrection of the Lord Jesus Christ, we can and should still testify to its truthfulness. In order to offer an adequate witness of the Lord’s saving grace, an individual must first have experienced the new birth combined with the witness of God’s indwelling Spirit (1 John 5:10).
Separation is the outcome of separation! When a nation (i.e., Israel in the Old Testament) or an individual (i.e., a believer in the New Testament) is set apart by the Lord, that nation (or person) has become disassociated with the rest of the world. Moses made this point in Exodus 33:16 when he said, “For wherein shall it be known here that I and thy people have found grace in thy sight? is it not in that thou goest with us? so shall we be separated, I and thy people, from all the people that are upon the face of the earth.” Separation is not something accomplished through diligence but occurs naturally after a person comes to know Christ as Saviour. Christians who remain attached to the world find little satisfaction with the things of the world or less appeal for the things of God.
