The Bible teaches who the Creator is. He is the Father according to the prophets:
“Have we not all one Father? Did not one God create us?” (Mal. 2:10 New International Version)
“No one has ever seen or heard of a God like you, who does such deeds for those who put their hope in him. But you are our father, LORD. We are like clay, and you are like the potter. You created us.” (Isa. 64:4, 8 Today’s English Version)
The Lord Jesus Christ attested to this:
“And this is eternal life, that they may know You, the only true God …
“Jesus spoke these words, lifted up His eyes to heaven, and said: ‘Father, the hour has come’.” (John 17:3, 1 New King James Version)
Even the apostles confirmed that:
“Yet for us there is but one God, the Father, from whom all things came and for whom we live.” (I Cor. 8:6 NIV)
Therefore, the creator taught in the Bible is the Father—the only true God.
With regard to nature or state of being, God is spirit, that is, He does not have flesh and bones (John 4:24; Luke 24:38-39) and thus, He cannot be seen (I Tim. 1:17). Yet, why must we believe that God exists even though He cannot be perceived by our senses?
“Ever since God created the world, his invisible qualities, both his eternal power and his divine nature, have been clearly seen; they are perceived in the things that God has made. So those people have no excuse at all!” (Rom. 1:20 TEV)
Whatever doubts, then, that people have in mind should be replaced by a solid faith that the Father is the One Who created us. God rewards those who have full faith in Him.
“And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him.” (Heb. 11:6 NIV)
Faith, then, is a very important requirement for salvation. But the faith that will save us is that which is coupled with works (James 2:22), for without work, faith is dead (James 2:17). Which work is this? This is the will of God that all men be gathered in Christ (Matt. 7:21; Eph. 1:9-10). How can men be gathered in Christ? This is by becoming members of the one body which is the Church headed by Christ (Rom. 12:4-5; Col. 1:18)—the Church Of Christ (Acts 20:28 Lamsa Translation).
Indeed, faith in God is very important. But having faith in Him is proven by our submission and obedience to His will.
