Watch for the "Suddenlies" by Joyce Meyer
...We will not all sleep [in death], but we will all be [completely] changed [wondrously transformed], in a moment, in the twinkling of an eye, at [the sound of] the last trumpet call....
~1 Corinthians 15:51-52 (AMP)
We all like "suddenlies," and as we draw closer to the end times, the Bible promises us a "season of suddenlies." When Jesus returns to earth for you, you will be changed, transformed "in the twinkling of an eye"—in other words, suddenly.
You don't have to be discouraged in your walk with God, because no matter what remains to be done in the transformation of your old man into your new man, it will be accomplished suddenly—at the appearing of Jesus in the heavenlies.
If Satan tries to tell you you're going to stay the way you are forever, he is lying. God is even now in the process of changing you from glory to glory, and whatever remains to be changed in you, He will one day do suddenly.
