“The Gospel is not a call to repentance, or to amendment of our ways, to make restitution for past sins, or to promise to do better in the future. These things are proper in their place, but they do not constitute the Gospel; for the Gospel is not good advice to be obeyed, it is good news to be believed. Do not make the mistake then of thinking that the Gospel is a call to duty or a call to reformation, a call to better your condition, to behave yourself in a more perfect way than you have been doing in the past …
Nor is the Gospel a demand that you give up the world, that you give up your sins, that you break off bad habits, and try to cultivate good ones. You may do all these things, and yet never believe the Gospel and consequently never be saved at all.” -- preacher Harry Ironside
The truth about Jesus is that the only way to be saved and to get into heaven and avoid being sent to eternal hell, is by believing in faith alone that Jesus, who is God, died on the cross for all our sins as FULL PAYMENT for all our sins, and then Jesus rose from the dead (1 Corinthians 15:1-4). Believe in Jesus alone for salvation, and you will be in heaven, no matter what! Salvation is a FREE GIFT that happens in a split second when you believe in Jesus alone to save you! It is impossible to lose or "leave" salvation (John 6:39-40, John 10:28, 1 John 5:13).
