Question: "How can I overcome my fear of the end of days?"
Answer: The best way to overcome a fear of the end of days is to be spiritually prepared for it. First and foremost, you must have a personal relationship with Jesus Christ in order to have eternal life (John 3:16; Romans 10:9-10). Only through Him can you receive forgiveness of sin and have eternity with God. If God is your Father, there’s really nothing to worry about (Luke 12:32).
Second, every Christian should live a life worthy of the calling we have in Christ. Ephesians 4:1-3 teaches, “Walk in a manner worthy of the calling to which you have been called, with all humility and gentleness, with patience, bearing with one another in love, eager to maintain the unity of the Spirit in the bond of peace.” Knowing Christ and walking in His will go a long way towards diminishing fear of any kind.
Third, Christians are told what will happen in the end, and it’s encouraging. First Thessalonians 4:13-18 notes,
But we do not want you to be uninformed, brothers, about those who are asleep, that you may not grieve as others do who have no hope. For since we believe that Jesus died and rose again, even so, through Jesus, God will bring with him those who have fallen asleep. For this we declare to you by a word from the Lord, that we who are alive, who are left until the coming of the Lord, will not precede those who have fallen asleep. For the Lord himself will descend from heaven with a cry of command, with the voice of an archangel, and with the sound of the trumpet of God. And the dead in Christ will rise first. Then we who are alive, who are left, will be caught up together with them in the clouds to meet the Lord in the air, and so we will always be with the Lord. Therefore encourage one another with these words.
Rather than fear the future, we are called to anticipate the future with joy. Why? In Christ, we will be “caught up” to meet Him and we “will always be with the Lord.”
Further, Scripture says we do not need to fear Judgment Day: “By this is love perfected with us, so that we may have confidence for the day of judgment, because as he is so also are we in this world. There is no fear in love, but perfect love casts out fear. For fear has to do with punishment, and whoever fears has not been perfected in love” (1 John 4:17-18).
The apostle Peter reveals that, even if our future holds suffering, we need not fear: “But even if you should suffer for righteousness' sake, you will be blessed” (1 Peter 3:14). Peter and many other early believers endured much hardship and even death because of their faith in Christ. Suffering is not to be feared; it is a blessing when it is borne for the name of Jesus.
Those who do not know Christ do not have the promise of peace for the future. For them, there is a real concern because they have not settled the issue of where they will spend eternity. Those who do know Christ do not fear the end of days. Instead, we strive to live a life worthy of our calling, live with confidence, suffer patiently, anticipate Jesus’ return, and rest in the knowledge that our times are in His hands (Psalm 31:15).
