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.

Therefore, Jesus may come back tomorrow, next month, next year or 100 years from now. So what does this mean for you and me? Always be ready for the second coming of Jesus Christ. Watch and focus on Jesus because the devil is seeking to distract mankind from understanding the signs and closeness of Jesus’ coming. Why is Jesus taking so long to come back? Jesus is patiently waiting to come back, because He is giving humanity as much time as possible to choose and follow Him. 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.

Will He appear spiritually to only a select few? Will Jesus’ second coming only be in certain physical locations? Will Jesus appear in the desert? Jesus warned about deceptions in the last days. In fact, in Matthew 24:4-5, Jesus cautions believers not to be deceived by people coming in the name of Jesus claiming to be Christ. Therefore, our only safeguard is to turn to the Bible alone for answers. Will Jesus come back secretly? Many people ask, how many people will see Jesus when He returns? Christ’s second coming will be bright, loud and glorious. This event cannot be hidden, every human on planet earth will see Jesus. He will come back personally and literally. Revelation 1:7 says, “Behold, He is coming with clouds, and every eye will see Him.” There will not be a person on earth who is unaware of Jesus’ return. Jesus Himself describes the manner of His coming.
