8 But since we belong to the day, let us be sober, putting on faith and love as a breastplate, and the hope of salvation as a helmet. 9 For God did not appoint us to suffer wrath but to receive salvation through our Lord Jesus Christ. 10 He died for us so that, whether we are awake or asleep, we may live together with him. 11 Therefore encourage one another and build each other up, just as in fact you are doing.– 1 Thess.5:8-11 NIV
We are saved by grace through faith, nothing else is required for salvation. That faith produces love and hope. Love because Jesus loved us enough to die for each one of us and His love shines through us to draw others to Himself. It produces hope in a world where there is no other hope. The death and resurrection of Jesus assures us that we will not have to go through the wrath that is coming. We are saved from an eternity of punishment and saved to an eternity of living together with Jesus. When we repented, we received Jesus as our Savior. He not only wants to be our Savior but, He wants to be Lord of our lives as well. This is necessary so that we allow Him to change us into His image. While salvation is instant, being changed is a life long process called sanctification. We are “set apart” to become holy. A part of this process is words and works that are worthy of the calling to be holy. So, as Paul says here, we should encourage and build each other up. We should also be doing the same things that Jesus did while He was here. This shows others that we believe in Jesus Christ and are committed to following His example.
12 Very truly I tell you, whoever believes in me will do the works I have been doing, and they will do even greater things than these, because I am going to the Father. 13 And I will do whatever you ask in my name, so that the Father may be glorified in the Son. 14 You may ask me for anything in my name, and I will do it. — John 14:12-14 NIV
