God’s call to holiness is not optional for any believer. Holiness is the standard God set for us in the beginning and continues to expect from us (Leviticus 19:2; 1 Peter 1:15–16). When we love the Father, we will desire to do what pleases Him because we all want to be counted like Paul when we die (2 Timothy 4:7).
We all want to run the race well and hear Jesus speak the words, “Well done, my good and faithful servant; enter into my rest” (Matthew 25:21). We dare not approach Heaven with stained garments uncleansed by the sacrificial blood of Christ (Hebrews 10:10). Sanctification always follows true repentance, so if we aren’t concerned with holiness, it is hard to conceive of our repentance as genuine.
