When Jesus was down here, it was evident that He wasn't here for ever. But while He was here, there was one thing He made abundantly clear. He will return.
He spoke about it often. He told parables about it. Many books of the Bible talk about it. Some devote whole chapters to it.
The book of Revelation, speaking in prophecy about that time, says "Let us be glad and rejoice and give him glory, for the marriage of the Lamb has come, and his wife has made herself ready" (Rev 19:7). Jesus is the Heavenly Bridegroom; those who know Him are His bride. One day He will come to take them home.
Notice it doesn't say "will hope to be ready" or "will make herself ready," but "has made herself ready." For most brides, their wedding day will be the most important day of their lives. You can't just walk into a church and get married in your lunch hour. There are preparations to be made: the church to book, bridesmaids to be chosen, bridal wear to be selected and the reception to arrange.
So how do you make yourself ready for His coming?
You must make sure that Jesus has first place in your affections. Not your husband. Not your wife. Not your children. Not anything else. But Jesus. If you want to have a successful marriage, don't put your spouse first. Put Jesus first, and everything else will fall into place.
You need to have a longing for that day. Before you were married, do you remember how you counted the days to your wedding? Hebrews says He will appear a second time "to those who eagerly wait for Him." Those who love Him are strangers and pilgrims in this world. They have another home being prepared specially for them. And it's much better than the one they have now. Each day they spend here is one day less and one day nearer.
And then we need to be busy doing what we're expected to be doing. The Scripture in Revelation that says "the marriage of the Lamb has come, and his wife has made herself ready" goes on: "And to her it was granted to be arrayed in fine linen, clean and bright, for the fine linen represents the righteous acts of the saints."
Live today as though today is all you have. After all, we have no guarantee that we'll still be here tomorrow.
"Behold, I come quickly!" (Rev 3:11).
