The Bible is filled with proofs of the Lord's timing. I also imagine that the believers in every generation have been waiting (and even expecting) the Lord's return. Remember in Acts 1:6, shortly after Jesus' resurrection, some of the disciples were already asking, "Lord, are you at this time going to restore the kingdom to Israel?" But Jesus answer was pointed, "It is not for you to know the times or dates the Father has set by his own authority. But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth." There are signs, like the regathering of the jews back to the nation of Israel in Ezekiel chapter 37. However, many of the signs are quite interpretive, and are sometimes not realized until AFTER their fulfillment. One of the most interesting signs that seems to have been fulfilled is the found in 2 Peter 3.Verse 4:"They will say, 'Where is this 'coming' he promised? Ever since our fathers died, everything goes on as it has since the beginning of creation.'" Lately, I have heard alot of people, both secular and churched (and even ministers) saying this. My answer to them is this: Regardless of whether the Lord is coming today or in a thousand years, we should still be prepared to meet him at any moment. Most people don't live to be 120 years old. But even 120 years is short compared to the inescapable eternity that awaits us when we breathe our last breath. Verse 8 continues: "But do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day. The Lord is not slow in keeping his promise, as some understand slowness. He is patient with you, not wanting anyone to perish, but everyone to come to repentance."The important thing is that we live our lives prepared to meet the Lord at any moment!Verse 11 and 14:"Since everything will be destroyed in this way, what kind of people ought you to be? You ought to live holy and godly lives as you look forward to the day of God and speed its coming.""So then, dear friends, since you are looking forward to this, make every effort to be found spotless, blameless and at peace with him."Should we give up the wait? By no means! Its just that the preparation for eternity should not depend on the timing of the Lord's return. It should depend on our relationship with him right now. The purpose of most of the Scriptures concerning the Lord's return deals with the very matter of being READY.Matthew 24:42-44"Therefore keep watch, because you do not know on what day your Lord will come. But understand this: If the owner of the house had known at what time of night the thief was coming, he would have kept watch and would not have let his house be broken into. So you also must be ready, because the Son of Man will come at an hour when you do not expect him."Keith Green once said about the debate concerning the pre-trib/post trib Rapture:"PRAY for Pre, but PREPARE for Post." The same thing applies to life. You could say, "PRAY that the Lord comes today, but PREPARE for a longer stay."Even so, come Lord Jesus! :-)
