Don’t go against your conscience. Or your faith could be shipwrecked. 1 Timothy 1:19. Your faith is like a ship, that is meant to take you to a certain destination – ultimately heaven – but there are also divine situations that your faith can take you to in this life. If your faith is shipwrecked, your faith is broken and until and unless your faith is rebuilt, your faith won’t take you anywhere. So you could miss heaven.
So don’t violate your conscience. Don’t deliberately sin. There are very strong warnings in the Bible about the danger of wilfully sinning, and continuing in sin, without repentance. See for example Hebrews 10:26-39. It happens a lot.
Hi my name is Michael Fackerell, founder of this site. It is created to help you know Jesus and get a great eternal reward from God Almighty. 
I see some born again Christians who are led to believe Matthew 18’s been found to be untrue. They believe the words of some self proclaimed messenger is to be believed instead of our Lord Jesus Christ guidance which is eternal. How can we believe false messengers instead of Jesus? He warned us, “Do not let anyone deceive you… They’ll come saying they believe in me…” And I believe they do believe in Jesus, but as the scripture foretells, “because of the great level of sin, their hearts will grow cold…” (paraphrasing mine) I’ve done this. There’s so much sin, both outside and inside the Church, and I hate it, and Jesus also hated and hates sin. But He loves sinners like us and takes us through repentance according to His Word, because He’s all about redemption which only happens through the power of God, the Love of God and the Mind of Christ. It’s possible only with God, but it is possible.
