1. Steadfast Christians are deeply concerned for the welfare of fellow believers.
1 Thessalonians 4:13
Brothers and sisters, we do not want you to be uninformed about those who sleep in death, so that you do not grieve like the rest of mankind, who have no hope.
Therefore, as we have opportunity, let us do good to all people, especially to those who belong to the family of believers.
Be devoted to one another in love. Honor one another above yourselves.
A new command I give you: Love one another. As I have loved you, so you must love one another.
2. Steadfast Christians have hope that fellow believers who have left this world are safe and well with Christ.
1 Thessalonians 4:14
For we believe that Jesus died and rose again, and so we believe that God will bring with Jesus those who have fallen asleep in him.
2 Corinthians 5:1-9
For we know that if the earthly tent we live in is destroyed, we have a building from God, an eternal house in heaven, not built by human hands. 2 Meanwhile we groan, longing to be clothed instead with our heavenly dwelling, 3 because when we are clothed, we will not be found naked. 4 For while we are in this tent, we groan and are burdened, because we do not wish to be unclothed but to be clothed instead with our heavenly dwelling, so that what is mortal may be swallowed up by life. 5 Now the one who has fashioned us for this very purpose is God, who has given us the Spirit as a deposit, guaranteeing what is to come. 6 Therefore we are always confident and know that as long as we are at home in the body we are away from the Lord. 7 For we live by faith, not by sight. 8 We are confident, I say, and would prefer to be away from the body and at home with the Lord. 9 So we make it our goal to please him, whether we are at home in the body or away from it.
3. Steadfast Christians are encouraged that those who physically die in Christ will not miss any of the glory of Christ’s second coming.
1 Thessalonians 4:15-18
According to the Lord’s word, we tell you that we who are still alive, who are left until the coming of the Lord, will certainly not precede those who have fallen asleep. 16 For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first. 17 After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air. And so we will be with the Lord forever. 18 Therefore encourage one another with these words.
