The Biblical order is sonship/justification, then service/sanctification. Those who reverse this biblical order are putting the proverbial "horse before the cart," and are confusing service to God the Father as sons, with service to become adopted sons. Those who make statements such as "make Jesus Lord of your life", "turn your life over to Jesus, give your life to Jesus", despite the fact that the heart of the gospel is the Lord Jesus Christ giving His life for us, and has nothing to do with us giving him anything, make this deadly error. The LORD God needs nothing from us(Acts 17:25 KJV, Job 35:7 KJV, Haggai 2:8 KJV) and is not, and will not, condition/make "giving our life to Him"(service) the basis for His acceptance of us. Again, The LORD God has accepted the Lord Jesus Christ's voluntary sacrificial offering of His life, not ours, as proptiatory(satisfactory). All service is a priviledged responsibility given as a gift to those who have been declared adopted sons by faith in the finished and faithful work of the Lord Jesus Christ.
Holy means "sanctified"=set aside for God's purpose. But God only uses those instruments that are His sons, and "saints" describes those who are already justified=His="in Christ". And the LORD God would have us know this biblical order in Corithians-Paul calls the Corinthians, the most carnal, dirty, lustful group of believer what? Saints-not sinners.
Consider the book of Galatians, which is a stern, severe, corrective, and solemn message-there is no word of commendation, praise or thanksgiving. Paul's "heart" is laid bare here as the letters are peppered with deep emotion and strong feeling. This is his "fighting epistle"-he is on a war path, with no tolerance for legalism! It is the declaration of freedom from all types of legalism. While Romans was from Paul's "head" with its lawyerly, systematic treatise on justification by faith, and faith alone, Galatians was from his heart. It is the boldest, strongest declaration and defense(as is this brilliant, humble post) of the doctrine of justification by faith in and out of the scriptures, and, as such, is God's polemic on behalf of the most vital truth of the Christian truth against any attack. That is, not only is a sinner saved by grace through faith(not commitment), but the saved sinner lives by grace(sanctification=commitment=the Christian "walk"). But we must not confuse justification(the declaration of righteousness) with sanctification! Yes, we are saved from the penalty of sin(justification), the power of sin(sanctification), and the presense of sin(glorification), but these are not equivalent biblical doctrines, and people are perverting the gospel of Christ by putting the proverbial "horse before the cart", i. e., they are placing sanctification=commitment=give your life to Christ in the wrong biblical order-as a "prerequisite" to justification, or as the means to justification. No, No, No!! Interestingly enough, Paul had nothing but condemnation for the Galatians, and yet, for the Corinthians, as mentioned, the most carnal bunch of Christians, who were engaged in adultery, drunkeness, gluttony.....he had words of encouragement, and never questioned their justification, as witnessed by his continual reference to them as "in Christ", and as saints. This should be an object lesson for us all, and should cause each of us to cry with joy and praise for the truly amazing grace bestowed upon e! ach one of us wherby we are made "...accepted in the beloved...."(Ephesians 1:6 KJV) by this great God of ours(Psalms 145:3 KJV). And this should be our motivation to "...walk worthy of the vocation wherewith ye are called...."(Ephesians 4:1 KJV), "..walk worthy of the Lord unto all pleasing, being fruitful in every good work, and increasing in the knowledge of God...."(Colossians 1:10 KJV), "...walk worthy of God, who hath called you unto his kingdom and glory...."(1 Thessalonians 2:12 KJV), "..walk and to please God, so ye would abound more and more...."(1 Thessalonians 4:1 KJV),."...as children of light...."(Ephesians 5:8 KJV), which is our "....reasonable service...."(Romans 12:1 KJV) as sons.
