For there is one God, and one mediator between God and men, the man Christ Jesus; Who gave himself a ransom for all, to be testified in due time. 1 Timothy 2:5-6 KJV
Jesus declared Himself to be the only way an individual can approach God.
Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. John 14:6 KJV
He also declared that He too was God. The book of Acts also declares that the Holy Spirit is God. Jesus is very God and very man concieved by the Holy Ghost, yet called the only begotten Son of God. Born of a virgin. Here in lies the mystery of Elohim, One God in plurality, Three in One: Father, Son, and Holy Ghost.
The word coined to express this Triunity is the word Trinity. Though the word, Trinity, is not found in the Bible, it is an accurate word describing the eternal Godhead. One “God in three Persons, Holy Trinity.”
God, in the Person of the Son gave Himself as a sacrifice for lost humanity. Each must turn to Him in repentance and receive Him to be saved.
