Would you like to be as you are today forever, without change? One of the awful realities for the sinner who dies in his sins is the fact that he will spend eternity without change in the dreadful condition of having the desires and unbelief of his unchanged, sinful nature and have no means to satisfing them even temporarily. Even his desire to change his state of torment with a sip of water will not satisfied.
In contrast, we who are believers have the wonderful opportunity gaze upon Christ as he now is in glory and be changed each day by the Spirit to be more like Him. The transformation will be complete when we are raptured and see Him as he is. Then being like Him, we shall never need to change again, nor will we ever want to.
