For I determined not to know anything among you except Jesus Christ and Him crucified. -1 Corinthians 2:2 NKJV
So many doctrines and opinions are used to separate brothers and sisters in Christ. Not only is the work of advancing the kingdom left undone, but Satan’s work is often accomplished in the process. How much more simple to preach the message of salvation given to us by our LORD through His death and resurrection. Keep it simple. Share the gospel. It must begin with that before there is any point of discussing other doctrine (important though it may be).
