The second coming is soon. In fact, Jesus promised His disciples that He would come again. In My Father’s house are many mansions; if it were not so, I would have told you. I go to prepare a place for you. When is Jesus coming back? Why is Jesus taking so long to come back? Will Jesus come back secretly? How should we live while we wait? How will Jesus come back? Will the angels come back with Jesus? Why is Jesus coming back? When is Jesus coming back? Jesus will come back soon. However, no one knows the exact time when Jesus is coming again. Mark 13:32 says, “But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father.” Interestingly, the disciples asked Jesus the same question just before He returned to heaven. At that time, Jesus told them it was not for them to know the times or seasons which are in the Father’s authority.

Jesus wants as many people as possible to repent and return to heaven with Him. 2 Peter 3:8-9 says, “But, beloved, do not forget this one thing, that with the Lord one day is as a thousand years, and a thousand years as one day. What is the rapture? What are the seven deadly sins? Warnings about the second coming of Jesus? There are many confusing non-biblical theories about the second coming of Christ which distract many people.
