The Bible is the infallible Word of God and the authority for salvation and Christian living. (See II Timothy 3:15-17. John 1:1)
Everyone has sinned and needs salvation.
Salvation comes by grace through faith based on the atoning sacrifice of Jesus Christ. That you must be born again. (See Romans 3:23-25; 6:23; Ephesians 2:8-9;
& John 3:3-5.)
There is one God, who has revealed Himself as our Father, in His Son Jesus Christ, and as the Holy Spirit. Jesus Christ is God manifested in flesh. He is both God and man.
(See Deuteronomy 6:4, Ephesians 4:4-6, Colossians 2:9,
I Timothy 3:16 & John 1:14)
Who is God?
As Christians we are to love God and others. We should live a holy life inwardly and outwardly, and worship God joyfully. The supernatural gifts of the Spirit, including healing, are for the church today. (See Mark 12:28-31,
II Corinthians 7:1, Hebrews 12:14, I Corinthians 12:8-10,
& Acts 2:6-8)
