In John 17:17-19 Jesus prayed that the Father would sanctify the disciples in the truth, God’s word is truth. Just what does it mean to be “sanctified?”
The word sanctified means “to be clean, consecrate, dedicate, to make holy.” So Jesus asked the Father to make His disciples holy. Guess what? He did!
Through Jesus’s being crucified, buried and raised again, and our being joined to Him, we have been Sanctified. God has set us apart from the world and made us holy for His purposes.
In many of the Apostle Paul’s letters he addresses the reader as “Saints.” The word “Saint” means “holy ones.” While many times we may not “feel” like we’re holy, God says, I have reconciled you to me in Jesus’s fleshly body through death, in order to present you before Me holy and blameless and beyond reproach (Colossians 1:21-22).
You simply can’t make yourself holy. God is the one who has done this “It is by His doing that you are in Christ Jesus, who became to us “sanctification.” Sanctification isn’t something God gives us rather Christ Himself is our sanctification. If you are “in” Christ, you have come “out” of the world!
Many see sanctification as a process and I understand why. But let me describe it to you using marriage as an analogy. When my wife and I were married, the moment we said, “I do” we were as married as we were ever going to be. As the years roll on we are never more married than we were in the moment we said, “I do.” On the other hand, there has been quite a learning curve about what it means to be married. I think this is the “process” part of sanctification.
The Apostle Paul instructs us to “be not conformed to the world but be transformed by the renewing of our minds” (Romans 12:2). The reason why is we are no longer “of” the world. Since we have been sanctified (set apart) from the world, we need to start seeing and understanding things from God’s viewpoint. Stop thinking and behaving as the world does and begin to see yourself as God sees you and that’s holy and blameless in His Son Jesus Christ.
