Behold, I come as a thief. Blessed is he that watcheth, and  keep his garments, lest he walk naked, and they see his shame. Revelation 16:15  Jesus will return unexpectedly, so we as Christians must be ready for His return. We can prepare ourselves by standing firm in temptation and by being committed to God’s moral standards and His spiritual laws. We must watch daily, because we don’t know the day, time or hour of His return.  When He returns, our souls must be anchored in the Lord and in His word, there will not be  time to repent, and make excuses; this is why we have been given instructions to follow by the Word of God. A thief never informs you of when he’s going to enter your house or take your car, before you know it the thief will have  came and gone, and that’s the way the Bible has instructed Jesus will be, as a thief.
