God’s Salvation can mean saved from something (deliverance) or for something (redemption). Paul preached that salvation comes through the death of Christ on the cross which redeemed sinners from death and for a grace-filled life. More has appeared in Jesus is the Messiah whose life, death, and resurrection are God's saving act for humanity More, whose self-giving love redeems sinners and shapes a community characterized by good works.
The Christian message appears here in a nutshell. The passage includes reference to past, present, and future. In the past, the Grace is the unmerited gift of God's love and acceptance. In Martin Luther's favorite expression from the Apostle Paul, we are saved by grace through faith, which means that God showers grace upon us even though we do not deserve it. More of God appeared; Christ gave himself. In the present, that grace forms godly people. The future will reveal that for which Christians hope, namely the full manifestation of God’s glory in Christ.
This salvation is for all. Though Titus and the churches on Crete have enemies, God’s grace extends beyond the battle lines of current conflicts to embrace all.
