Paul summed up everything a believer needs to know in order to be on the salvation path in 2 verses!
In 2 Corinthians 4:3-5 Paul tells us that Messiah is the image or exact replica of YHVH God the Father.
In Romans 8:29 Paul tells us all men should become the image or exact replica of Messiah.
Whatever Messiah did, that is what we should do.
However Messiah lived, that is how we should live.
In many places Messiah said “follow me” and of course everyone knows that is about becoming a disciple of Messiah.
If you study, you find a disciple is one who becomes the image of his teacher/master.
Messiah kept all THE LAW of YHVH God His Father, kept YHVH’s Sabbath and YHVH’s Feasts.
The only way anyone can enter into heaven is to be like Messiah and DO what he Did.
THE LAW of YHVH God = The Gospel. That is Hebrews 4:2
Shalom!
