Being in the presence of God is wonderful beyond description. Sometimes a picture, or during special moments in prayer, I catch a whiff of what that will be like. Then it makes my spirit soar. But, I think, only when we are before the throne of God will we truly know what the abundant life is all about.
“I came that they may have life, and have it abundantly.” (John 10:10)
The absence of God is a horror of equal dimension in the other direction. Only those caught in Hell will realize the depth of this hopelessness. There is no picture I have to convey this, so I will only put forth the words of Jesus in describing such a place:
“But woe to that man who betrays the Son of Man! It would be better for him if he had not been born.” (Mark 14:21)
