ONLY ONE GOD: True Christian doctrine is that there is only one God who has ever existed anywhere, anyplace, anytime. There is no God formed before God; there will be no God formed after God (Isaiah 43:10). God doesn’t even know of any other gods (Isaiah 44:8). There is only one God in existence in the entire universe. Just one. This is called monotheism.
THE TRINITY: God is a trinity of persons: The Father, the Son, and the Holy Spirit. The Father is not the same person as the Son. The Son is not the same person as the Holy Spirit. The Holy Spirit is not the same person as the Father. They all are eternal, divine, and omniscient.
Objections to the Trinity are that it is not logical. Logic should not rule scripture. If it is from God, there will be things in it that are difficult to understand. Additionally, the fingerprints of God are seen all over creation. In Romans 1:20 it says that the invisible attributes of God are clearly seen in creation. Creation is made up of a trinity of trinities: time, space, and matter. Time is past, present, and future. Each “part” is different, yet they are all of the same nature: time. Space is height, width, and depth. Each “part” is different, yet they are all of the same nature: space. Matter is solid, liquid, and gas. Each “part” is different, yet they are all of the same nature: matter.
JESUS: Jesus is the second person of the Trinity. Jesus is both God and man. He is fully God and fully man (Col. 2:9). He was in the form of God, emptied Himself, and became a man (Phil. 2:5-8). As the God man, He is the mediator (1 Tim. 2:5). Jesus was not created (John 1:1-3), but is the creator of all things (Col. 1:16-17).
SALVATION: Salvation, or the forgiveness of sins, is something that is given to you by God. It is a free gift (Rom. 6:23). The sinner is made righteous in God’s eyes solely by the faith that the believer has in the sacrifice of Jesus on the cross. Justification, or being declared righteous, is accomplished by faith (Rom. 5:1). Our works play no part in salvation. If our works could play any part at all, then Jesus died needlessly (Gal. 2:21).
The truth is important not because it is simply true. It is important because truth is what defines who and what we believe in. Faith is vital. But faith placed in something false is the same as having no faith at all. Faith is only as good as the object in which it is placed. That is why it is important to have the true Jesus -the one of the Bible. Eternity is a long time to be wrong. Especially about Jesus. (MATT SLICK)
