Maranatha ! Come Lord Jesus come. When you see these things take place look up for your Redemption draweth near. The Parables of Jesus are for His faithful ones to be ready for He will come like a thief in the night when you least expect. We are to be the wise virgins having out lamps full and ready- to be prepared anticipating His Return to His bride.
I think you will find that the surprise only applies to those who are unbelievers, or those Christians who are asleep. . Those of us who have an ongoing relationship with Jesus and are watching for His return, will not be surprised.
KJV 1 Thessalonians 5:2-6
2 For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
3 For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.
4
But ye, brethren, are not in darkness, that that day should overtake you as a thief.
5 Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness.
6
Therefore let us not sleep, as do others; but let us watch and be sober.
