The great mystery (rapture)

 Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, 1 Corinthians 15:51

One promise Christ has assured all saints is his second coming (rapture). Christ has often talked about his second coming as a sudden caught up of the saints; we know He never told us about the time but he gave us signs about the eminent of the rapture which are; wars, rumors of wars, pestilence (epidemics or pandemic of diseases) these are signs already manifesting in our present era; of which we are living witnesses, and the gospel of Christ preach everywhere all over the world. But the Devil seeing this signs, is working desperately to shift our focus from these signs to the things of the world of which are Written in  2 Timothy 3:2 “For men shall be lovers of their own selves, covetous, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy,” The Scripture made us to know his time is short. Christ has promised to take us (saints) from the surface of the Earth before the End comes and thereby changing us from mortal to immortal beings (everlasting) just like him as it is written in 1Corinthians 15:51 “Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed”, The word “sleep” meant death; that is we shall not all die but be raptured. Believers should be earnestly awaiting the second coming of our lord Jesus as it can happen at any time from now. Earnestly expecting his second coming is a faith we have in Christ even believers in the grave that had this faith will be resurrected to meet him in the sky. 

Conclusion:

We should be spiritual conscious of Christ second coming, though such a mystery has never happened before but through faith in Christ we believe he is coming again to take his saints.
