1Co 15:19 If in this life only we have hope in Christ, we are of all men the most pitiable.
Christians have the hardest life of all men. They live in a foreign land, among the enemies of their God. For God's sake they are "killed all day long." They are martyred for love, they are persecuted for good works. Of all men we should be the saddest, gloomiest, and most hopeless... yet:
John 16:33 "These things I have spoken to you, that in Me you may have peace. In the world you will have tribulation; but be of good cheer, I have overcome the world."
Romans 8:36-37 "As it is written: "For Your sake we are killed all day long; We are accounted as sheep for the slaughter." Yet in all these things we are more than conquerors through Him who loved us."
How are we more than conquerors? How do we have peace that passes all understanding?
Romans 8:35-39 "Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? As it is written: "For Your sake we are killed all day long; We are accounted as sheep for the slaughter." Yet in all these things we are more than conquerors through Him who loved us. For I am persuaded that neither death nor life, nor angels nor principalities nor powers, nor things present nor things to come,nor height nor depth, nor any other created thing, shall be able to separate us from the love of God which is in Christ Jesus our Lord."
1 Corinthians 15:51-53 "Behold, I tell you a mystery: We shall not all sleep, but we shall all be changed–– in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal must put on immortality."
Nothing will separate me from the love of my Father in heaven. I will recieve a glorified and ressurected body, when He comes to judge the world, with which to enjoy Him forever. How could I not be happy?
