The entire Bible is the inspired revelation of God to man.
The Lord Jesus Christ is God and a co-equal with the Father and the Holy Spirit. By Him the Father created all things.
The Lord Jesus Christ became man by the miraculous operation of the Holy Spirit. He was without sin.
The Lord Jesus Christ, the Lamb of God, died willingly in the place of sinners, to become the redeemer of this fallen world, and the only Mediator through Whose atoning Blood we receive the forgiveness of sins.
The Lord Jesus Christ rose from the dead, appeared to His disciples, and returned to the Father. Now, in the Person of the Holy Spirit, He dwells in the lives of those who receive Him (His church).
The Holy Spirit is a co-equal member of the Trinity of God.
The Lord Jesus Christ is returning in person to earth. By Him, God will judge the world.
