Above you see the eight (8) steps to perfection of 2 Peter 1:5-7 laid out in reference to the Temple. The first step is Faith. In order to be justified, you must have faith that Jesus is able to wipe out your past sins. You must have faith that He, and He alone can pay the penalty for your PAST sins. With that deep and abiding faith, you enter the courtyard of the sanctuary.
After recognizing that Jesus is the Lamb who can take away your past sins, you then proceed to the second step at the water basin to wash your sins away. In the blood of Jesus, and through His power, you begin doing all the good you know how to do. You no longer do the sins of your past. You are born again and washed clean in the blood of Christ. You cannot continue in any KNOWN sin at this point.
Now you are entering the door of the Holy Place of sanctification and leaving justification behind. There is no more need for justification in your life at this point. Your past sins have been wiped out and thrown into the depths of the sea (symbolically of course). God no longer sees them. You are clean in His eyes. But this cleanness will not save you eternally. It only allows you to continue in the salvation process. That process is called sanctification.
In the sanctification process you have a job to do. You must start by eating of the flesh of Jesus, His body, by learning about Him. This is the third step, knowledge. You must learn all you can about this new life and how you are to live and obey it.
As you learn what you must do, you are entering upon the fourth step, self-control. As you drink of the blood of Jesus, you enter into His self-control. You practice what you are learning. But this is not to be an on-again-off-again thing. It is not a momentary self-control. This self-control must be maintained. It is not "once saved always saved" but a continuous eating and drinking from God's Word.
The fifth step is maintaining that self-control moment-by-moment, hour by hour, day after day, year after year. That is called perseverance. Through perseverance we no longer are sinning. When temptations arise, we use the self-control God has given us through His power to persevere in righteousness and say "no" to temptations. That is how we "follow" the example of Jesus.
This perseverance produces the sixth step of godliness. You are now living the sweet smelling, aromatic life of God. This is His perfection. Through godliness, or God-likeness, you are now fulfilling the two parts of the Ten Commandments. The first part of the Ten Commandments that you will begin to fulfill is step seven, brotherly kindness. This is "Love your neighbor as yourself". This brotherly kindness is what happens when you are fulfilling the last six of the Ten Commandments.
From here we demonstrate the eighth step. This step is the highest, or Agape, love. You are now fulfilling the first four of the Ten Commandments, love to God.
This diagram is the essence of the whole Bible. Everything in the Bible is simply a more detailed concept of this simple eight step process of getting to heaven. It has nothing to do with church, religion or denomination. It has everything to do with your personal relationship and work with God and His eight steps to His perfection.
"To those sanctified in Christ Jesus and called to be holy, together with all those everywhere who call on the name of our Lord Jesus Christ--their Lord and ours." 1 Corinthians 1:2.
"But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God." 1 Corinthians 6:11.
"It is God's will that you should be sanctified: that you should avoid sexual immorality; that each of you should learn to control his own body in a way that is holy and honorable, not in passionate lust like the heathen, who do not know God; and that in this matter no one should wrong his brother or take advantage of him. The Lord will punish men for all such sins, as we have already told you and warned you. For God did not call us to be impure, but to live a holy life. Therefore, he who rejects this instruction does not reject man but God, who gives you His Holy Spirit." 1 Thessalonians 4:3-8.
"May God himself, the God of peace, sanctify you through and through. May your whole spirit, soul and body be kept blameless at the coming of our Lord Jesus Christ." 1 Thessalonians 5:23.
"But we ought always to thank God for you, brothers loved by the Lord, because from the beginning God chose you to be saved through the sanctifying work of the Spirit and through belief in the truth." 2 Thessalonians 2:13.
"…Who have been chosen according to the foreknowledge of God the Father, through the sanctifying work of the Spirit, for obedience to Jesus Christ…". 1 Peter 1:2.
Grace saves us physically from immediate death. Justification does the same in a spiritual way. But neither will save you eternally.
Faith and Sanctification are the two vehicles that you must be in to be eternally saved. Grace and justification will get you to the vehicles, but you must open the doors of Faith and Sanctification and get inside. That is the only way you can have eternal life.
Keep in mind that these eight steps are to be constantly worked in "increasing measure". "For if you possess these qualities in increasing measure, they will keep you from being ineffective and unproductive in your knowledge of our Lord Jesus Christ." 2 Peter 1:8.
If you constantly work these eight steps in increasing measure, every day putting them into practice, then you will never sin again in your life. You will live the pure and perfect, sinless righteous life of Jesus. "For if you do these things, you will never fall." 2 Peter 1:10.
