We need a doctrinal affirmation of what a believer is actually supposed to believe and live it is ALL scripture
Point # 1
I recognize that there is only one true and living God (Exodus 20:2,3)who exists as the Father, Son and Holy Spirit, who is worthy of all honor, praise and worship as the Creator, Sustainer and Beginning and End of all things. (Rev.4:11, 5:9,10, Isaiah 43:1,7,21)
Point #2
I recognize Jesus Christ as the Messiah, the Word who became flesh and dwelt among us (John 1: 1,14) I believe that He came to destroy the works of the devil (I John3:8), that He disarmed the rulers and authorities and made a public display of them, having triumphed over them by the cross (Colossians 2:15)
Point #3
I believe that God has proven His love for me, because when I was still a sinner Christ died for me (Romans 5:8). I believe that He delivered me from the kingdom of darkness and transferred me to His kingdom and in Him I have redemption and the forgiveness of sins (Colossians 1:13,14)
ps: plenty more which I will add as I can
