I don’t want to be misunderstood; I agree entirely with Paul when he says:

For by grace are you saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.

Ephesians 2:8–9 KJ2000

So salvation is by grace through faith. We can’t achieve it by ourselves, we cannot do it by law-keeping, we cannot in any way get rid of our past guilt, we cannot create a circumstance in which God owes us salvation—none of that. But having come to Christ, through faith, how should we then lives our lives? Is there a way of life for a Christian after one has come to the faith? Is there a way we should go and a way we should not go? Is there a way of obedience to Christ and a way of disobedience to Christ? Does it make any difference which one of those ways we walk? Well, Jesus, in his Sermon on the Mount, said this:

Enter in at the narrow gate: for wide is the gate, and broad is the way, that leads to destruction, and many there be who go in there: Because narrow is the gate, and narrow is the way, which leads unto life, and few there be that find it.

Matthew 7:13–14 KJ2000
