God loves us so much that He has made a way for people to be saved from their sinful SELF. That way, Jesus' shed blood on a cross, has wiped out all the sins of the flesh for all people. It is totally fair in that it doesn't require a person to become perfect in their sinful bodies. It only requires that people believe Him.
In this age of God's grace a person has to put all their faith, trust, belief, and confidence in what Jesus (God) did on the cross. He paid our sin debt for us.
Today. in religions, men and women place their faith, trust, belief, and confidence in their own religious theology to save them. These are self-righteous who, like the Pharisees, want to make a show of themselves as being less sinful than others.
Luke 18:9-14 ---- The Parable of the Pharisee and the Tax Collector
9 Also He spoke this parable to some who trusted in themselves that they were righteous, and despised others:
10 "Two men went up to the temple to pray, one a Pharisee and the other a tax collector.
11 The Pharisee stood and prayed thus with himself,'God, I thank You that I am not like other men — extortioners, unjust, adulterers, or even as this tax collector.
12 I fast twice a week; I give tithes of all that I possess.'
13 And the tax collector, standing afar off, would not so much as raise his eyes to heaven, but beat his breast, saying, 'God, be merciful to me a sinner!'
14 I tell you, this man went down to his house justified rather than the other; for everyone who exalts himself will be humbled, and he who humbles himself will be exalted."
NKJV
If I am saved from all the sin in the world and not saved from my sinful self then there is no salvation.
