It's tempting to be afraid of Jesus' second coming. Jesus will come again to judge the earth, and this thought can cause fear in many people.
The key to banishing this fear of Jesus' second coming is to fully embrace Jesus' first coming.
St. Augustine explains this idea in a commentary on Psalm 95.
The way we approach Jesus' second coming is directly related to how we view God in the present time. If we love Jesus now, with our whole heart, we should have no cause for fear of when Jesus comes again.
We should look forward to ehe coming of Jesus at the end of time, or at the very least, at the end of our earthly life. Our hearts should long to see Jesus and to be with him for all eternity. If we have any fear in our heart of Jesus, we should look inside ourselves and see what kind of attachments we still have to this earth or to our sins.
Let us welcome Jesus' first coming, so that his second coming does not create any fear in our hearts.
