I have sometimes heard the charge from skeptics that Christians come off as thinking they are better than other people. This impression perhaps arises for at least two reasons: 1) because a professing Christian who does not understand the gospel actually DOES think they are better than non-Christians or 2) a true regenerate Christian who may be triggered/set off by something, forgets the gospel, and rashly in their pride says some things indicating they think they are better.
Either way, the fact is that we are not better. Not by a long shot. D. Martyn Lloyd-Jones once declared in no uncertain terms "Do you think that you deserve forgiveness? If you do, you are not a Christian."
A Christian is Saved By Grace
A sinner is saved when, by grace, they acknowledge that they have no righteousness of their own and trust in Christ's promise to deliver them from their guilt and captivity to sin.
"For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast." (Ephesians 2:8,9).
At our very best — we are but miserable sinners. We are not saved because we are better or more deserving than others, but are saved by God's mercy alone. It is true that God sets Christians apart and works holiness into their character but the Christian is one who remembers that any good character he/she may now have is only because of God's mercy. We had nothing to do with it. There is no hierarchy of merit in coming to the cross... No one gets to heaven because they are better than anyone else. NO ONE. We are all saved by Christ alone.
