All of us in Christ’s Church are called from darkness to light at salvation; and we are saved from the power of Satan; and we are being transformed into saints of God. That process in called consecration. Last week as we looked at the Church at Thyatira (Revelation 2:18-29), we saw that their consecrated lives were slipping because of compromise with sin and false doctrine.
Jesus called them to repent, to have a change of mind that would lead to a change in behavior. The letter to Thyatira is a challenge from Christ for His children of faith to do what is needed: repent of compromising their lives of sanctification.
