Mathew 25:46

Then these (unbelieving people) will go away into eternal (unending) punishment, but those who are righteous and in right standing with God (will go, by His remarkable grace) into eternal life.

It matters what we believe! Our choices must be firm on the Word of God and His teaching, not false doctrine or twisted teachings that lend toward the justification of sin. Faith is not to build up our feelings but to increase the strength of our spirits toward righteousness. Feelings change, but God and the Bible do not.
