We all need to emphasize that the doctrine we believe, teach, and practice is crucial to our salvation. Most denominational people don't think doctrine is important at all. But consider what II John verse 9 says:Whosoever transgresseth, and abideth not in the doctrine of Christ, hath not God. He that abideth in the doctrine of Christ, he hath both the Father and the Son.Did you see that? If we don't abide in (stay inside) the doctrine (teaching) of Christ, we don't have God. And we certainly can't be saved without God. Just the opposite is true. We can only be saved with/by/through God (John 14:6).So if you believe II John verse 9, then you believe that if you don't abide in Jesus' teaching, you will be without God and lost. False doctrine causes people to be lost spiritually (Galatians 1:6-9). We all need to make a decision about religious (Bible) doctrine. Are we going to take it seriously? Are we going to study to find out the truth, so that we can be made free from sin (John 8:32)? Or instead are we going to just ignore the issues, sticking our head in the sand, being deceived by the axiom that ignorance is bliss (Matt 13:15)?
