Righteousness

"We are now justified (aquitted, made righteous, and brought in right relationship with God) by Christ's blood. " Romans 5:9(AMP)[Also see Colossians 1:14 AMP]

We are made righteous through Christ's blood. One redemptive name of God (which describes His redemptive-relationship with us) is Jehovah-Tsidkenu. This means The Lord is our Righteousness.

"For our sake He made Christ {virtually} to be sin Who knew no sin, so that in and through Him we might become {endued with, viewed as being in, and examples of} the righteousness of God {what we ought to be, approved and acceptable and in right relationship with Him, by His goodness}." 1 Corinthians 5:21 (AMP)

Through the redemption of Jesus we can be found In Christ (Colossians 3:3, Ephesians 2:10). Through Christ's blood (redemption) we have been made righteous.

What makes someone righteous? Christ's blood
Do works make you righteous? No (Ephesians 2:9)
Can you become unrighteous because of your works? No

You have been made righteous by the blood of Christ. Your works cannot make you any more or any less righteous.

When we die and are with God will we be more righteous than we are right now? No

Jesus does not have to die again. He made us righteous by His blood. He doesn't need to do this again.

Therefore, Jesus took care on the "sin problem" on the cross. I used to worry about the possibility of dying before I was able to ask for forgiveness for any sin that I may have forgotten to ask for. I thought that sin stood in between me and God and therefore I would be unworthy to be with Him in eternity. But, Jesus took care of the "sin problem" on the cross, my sin does not make me less righteous.

Just like an earthly parent does not need their child to ask them for forgiveness before they are able to forgive their child, God does not need us to ask for forgiveness before He is able to forgive us. He has already washed away all of our sin, past, present, and future, on the cross (Acts 5:31, Ephesians 1:7). Why would we ask for forgiveness then? Because the act of asking for forgiveness is a part of a healthy relationship. When we are in relationship with the Lord we ask for forgiveness for hurting Him, not because we think He will hold it against us if we don't.

God has made us righteous through His blood. We are in right standing with God. The only requirement is to be found In Him. You are found in Him when you confess with your mouth and believe with your heart that Jesus rose from the dead for your justification (to make you right with God) (Romans 10:9). We are not unworthy anymore. We can approach God in confidence (Hebrews 4:16). We are right with God now.

"For by a single offering He has forever completely cleansed and perfected those who are consecrated and made holy." (Hebrews 10:14 AMP)

We are righteous, being made holy. We are made holy by renewing our mind (changing the way we think, rewiring our brain) to the truth of our righteousness. When we change our way of thinking to reflect what is already a reality in us. We are righteous in Him, live in this reality.
