Christians should pray to God the Father. Worship and to God the Father. At the same time, Christians can pray to Jesus Christ. Because Jesus Christ is the Mediator.
Worship is not the basic command given to Christians, it is “Love”. The basic commandment given to Christians is love and the actions that follow. Worship God in spirit and truth. Jesus Christ, his disciples and the early Christians worshiped God the Father in spirit and truth. Worship in spirit and truth is love and the actions that follow.
Worship of anything that is not God is sinful because it is untrue.
No other mediator can be accepted on earth. Jesus Christ is the only mediator between God and human.
