A significant percentage of westerners profess to know God and therefore call themselves Christians. Yet many of them do not believe in Jesus or His claim to be the Son of God. The fact is, a person cannot know the Father and be His child unless he or she has received Jesus Christ as Savior and entered into a personal relationship with Him.
Jesus is the doorway to salvation. It's not enough to "know God" in the sense of simply realizing there is a supreme Deity. Without faith in Jesus, it is impossible to come to the Father (John 14:6). Since God is holy, He can't tolerate sin in His presence. But all people are sinners (Ps. 53:3; Isa. 53:6). Jesus died in our place to pay our debt and thereby bridge the gap between impure man and holy God. Any person who receives His sacrifice for sin is forgiven, declared righteous, and welcomed into fellowship with God.
Jesus is the doorway to revelation. He was the earthly representation of His Father in heaven. Christ's life among men provides the most complete picture we have of the Father. Jesus' actions, choices, and teachings reveal how the Almighty thinks and what He desires from us.
Jesus said that He and His Father are one (John 10:30). Omitting Christ from religious beliefs or practice leaves people with an inaccurate view of the Creator. We are saved not by works but by faith, through grace (Eph. 2:8-9). And the faith God values is the belief "that Christ died for our sins according to the Scriptures, and that He was buried, and that He was raised on the third day according to the Scriptures" (1 Cor. 15:3-4).
