I believe and teach the same doctrine as taught by the Apostles in the book of Acts. God never changes (Malachi 3:6, Hebrews 13:8) and neither does His Church. There is only one Church, the Church that Jesus built and continues to build (Matthew 16:18), the one described in the book of Acts, which is the history of the early Church.
I believe that the truth of who Jesus is and what true salvation is, is a mystery hidden to most people including the religious of today. The Apostle Paul wrote; "But if our gospel be hid, it is hid to them that are lost" - 2 Corinthians 4:3. Jesus said "I am the door" (John 10:9), and "I am the way, the truth, and the life: no man cometh unto the Father, but by me" (John 10:14). There is no other way.
One Lord, One Faith, One Baptism
One God and One Lord: God said that He alone was God, Lord, and Saviour, and that there was none other (Isaiah 45:6, 45:21). God said in Deuteronomy 6:4 that He was One Lord. Zechariah 14:9 proclaims that the Lord would be Lord of all the earth and in that day there would be One Lord, and His Name One. 1 Corinthians 8:6 proclaims that the Name of that One Lord is Jesus.
One Faith and One Gospel: But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed (Galatians 1:8).
One Baptism: Matthew 28:19 declares that we are to be baptized in the NAME of the Father, and of the Son, and of the Holy Ghost. That NAME is JESUS (Acts 2:38, 8:12).
Here's my answer to the salvation question, in a mystery. Pray about it, study it out and let God reveal truth to you.
Here are a few verses that shed light on true Salvation through the Gospel:
