Most think "What they "believe" in Terms of Christianity" is of a personal nature, not to be shared with others which is "totally" against Scripture!
I Peter 3:15 says "...be ready ALWAYS to give an answer to every man that asketh you a reason of the HOPE that is in you..." So are they really "Christians?"
There isn't enough room to tell ALL of what I believe "A Disciple of Christ" should be other than to follow in Jesus' footsteps! How? Jesus came, fulfilled law (Galatians 4:4), left us a Comforter (Holy Spirit; John 14:26;16;13), effected the New Covenant wherein the Holy Spirit would "lead and guide us into ALL truth" so that we would no longer have to "work" but the Holy Spirit NOW "WORKS" changing us from "glory to glory" into His likeness" (II Corinthians 3:18)!
I believe JESUS is GOD (John 1:10; Revelation 1:8; Isaiah 43:10-13 & MANY more), which is THE GREATEST ALLEGORY in Scripture, baptism should be done in Jesus' Name as did the apostles AFTER THE CROSS (Acts 2:38; 19:5; + MORE), Water should be given for Communion vs wine or grape juice (Matthew 26:28; Luke 22:20; "IN MY BLOOD WHICH WAS "SHED" & "..when solider pierced His side; forthwith came there out blood and WATER;" (John 19:34) which was "SHED"), women preachers (Galatians 3:28), Marriage is acceptable ONLY in the sight of God "...ONLY IN THE LORD" (I Corinthians 7:39 speaks to 2nd but 1st should be moreso) for Marriage is a "mystery" as "Christ is to the Church (both Holy; Ephesians 5:32) and MORE!
In other words, I do not believe as "religion" does, but what a Disciple of Christ should do AFTER THE CROSS as written in His Word!
Bare in mind, we are currently under A NEW COVENANT for Jesus said in Jeremiah 31:33; Hebrews 8:10 and 10:16, that "...after those days (after He resurrects) He would "..put his laws in their mind, and write them in their hearts" which is precisely what He did on the Day of Pentecost (Acts 2:2) via the Holy Spirit! Afterward, the apostles did as JESUS (John 14:26; "IN MY NAME") told them to do! Why people believe it was Paul talking and not Jesus, I don't understand! Do they not "see" in Acts 2:42 the Disciples of Christ "...continued in the apostles' doctrine (which was not the apostles' but JESUS' Doctrine for He was "putting his laws in their minds and hearts?" Besides, Paul (Jesus) told us to "..follow my example, as I follow the example of Christ.." Blasphemy? Most would believe but it's in Scripture and MOST have not been taught!
