“But in those days, following that distress, “ ‘the sun will be darkened, and the moon will not give its light; the stars will fall from the sky, and the heavenly bodies will be shaken.’ Mark 13:24-25 NIV
So, you want to know when the second coming of Jesus Christ is at hand? Here he explicitly tells us. It will be immediately after the days of the tribulation. The signs will be ones that have never been seen before: the sun will be darkened, the moon shall no longer provide light, the stars shall fall from the sky, and the heavenly bodies will be shaken. See, it will be quite obvious when the Lord returns. These are signs which cannot be mistaken and their occurrence has been promised by our Lord. In the meantime we are to continue in our service to the Lord, sharing the gospel with those we meet. The Good News must be proclaimed unto all the nations!
