So being a Christian means recognizing you are flawed and a sinner, and can never match God's perfection. Ultimately you will be judged to be a sinner, no matter how few or small, and can only be saved through the blood sacrifice on the Cross. Does this mean you should stop trying to be a better person? Does Scripture say anything about pursuing self-growth?
I think our sins were judged on the cross, when we place our faith in Jesus as the son of God who died and rose again because of our sins then they are forgiven. So we have been judged as sinners and the price has been paid.
We are not saved by works or by self improvement.
We are saved by faith but it doesn't stop there. It doesn't give us a license to sin and do what we want.
Even after faith our efforts of self improvement or following certain rituals or rules does not continue to keep us saved. It's our faith in Jesus that continues to save.
So when people stand before God they will be judged. We find the scenario that Jesus gives when he separates the sheep from the goats.
The sheep enter the kingdom of God, the goats do not. What is interesting is that the sheep are told "My good and faithful servants" the sheep are surprised because Jesus praises them for the things they have done (works as such)
Jesus relates to them the things they have done for others as being the same as doing it to him.
Matthew 25:34-40
“Then the King will say to those on his right, ‘Come, you who are blessed by my Father, inherit the Kingdom prepared for you from the creation of the world. For I was hungry, and you fed me. I was thirsty, and you gave me a drink. I was a stranger, and you invited me into your home. I was naked, and you gave me clothing. I was sick, and you cared for me. I was in prison, and you visited me.’
“Then these righteous ones will reply, ‘Lord, when did we ever see you hungry and feed you? Or thirsty and give you something to drink? Or a stranger and show you hospitality? Or naked and give you clothing? When did we ever see you sick or in prison and visit you?’
“And the King will say, ‘I tell you the truth, when you did it to one of the least of these my brothers and sisters, you were doing it to me!’
As for the goats.
Matthew 25:41-46
“Then the King will turn to those on the left and say, ‘Away with you, you cursed ones, into the eternal fire prepared for the devil and his demons. For I was hungry, and you didn’t feed me. I was thirsty, and you didn’t give me a drink. I was a stranger, and you didn’t invite me into your home. I was naked, and you didn’t give me clothing. I was sick and in prison, and you didn’t visit me.’
“Then they will reply, ‘Lord, when did we ever see you hungry or thirsty or a stranger or naked or sick or in prison, and not help you?’
“And he will answer, ‘I tell you the truth, when you refused to help the least of these my brothers and sisters, you were refusing to help me.’
“And they will go away into eternal punishment, but the righteous will go into eternal life.”
What is interesting is that the sheep in a sense question Jesus with and say we never fed you and the goats with we never saw you hungry, and Jesus says "What you did for someone else you did for me and want you didn't do for someone else you didn't do for me"
So to me it seems that the sheep when judged are considered righteous not because of a prayer along the lines of "I beleive in Jesus" but judged because that prayer shows evidence of what they prayed.
The goats never saw Jesus.
Matthew 7:21-23
“Not everyone who calls out to me, ‘Lord! Lord!’ will enter the Kingdom of Heaven. Only those who actually do the will of my Father in heaven will enter. On judgment day many will say to me, ‘Lord! Lord! We prophesied in your name and cast out demons in your name and performed many miracles in your name.’ But I will reply, ‘I never knew you. Get away from me, you who break God’s laws.’
It doesn't seem like they fed the poor, welcomed in a stranger, gave someone a drink, visited the sick.
Self improvement is not the issue, a genuine belief in Jesus is the issue. Jesus knew that we could not self improve to the extent to meet Gods standard. Jesus himself said that he must go back to the Father so the Holy Sprit must come to convict the world of its sin, that sin being unbelief in him. When we come to place of beleiving in him we have the Holy Spirit in us who teaches us the way Jesus. We don't sit back and say "Ok Holy Spirit you take over and I'll sit back and we don't say "Ok now I will embark on a programe of self improvement" we have to work with the Holy Spirit to become more like Jesus"
We are saved to do good works.
Ephesians 2:10
For we are God’s masterpiece. He has created us anew in Christ Jesus, so we can do the good things he planned for us long ago.
We love because he first loved us.
