Only those who are following Christ’s example of walking in obedience to God’s law are in Christ (1 John 2:6).
Hi @Soyeong
We should only look to our works as an evidence. Once we cross the line and look to our works to justify ourselves, this parable in Luke applies.
Luke 18:9-14 Also He spoke this parable to some who trusted in themselves that they were righteous, and despised others: "Two men went up to the temple to pray, one a Pharisee and the other a tax collector. 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. I fast twice a week; I give tithes of all that I possess.' 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!' 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."
The sinner was justified. The tax collector who obeyed God's Law perfectly (at least in his own mind) wasn't. Obeying God wasn't the sin. It was trusting in obeying God that made the tax collector not justified. The sinner who trusted in Jesus was justified.
The merits that justify us before God are all from Jesus.
