“Being darkened in their understanding, excluded from the life of God because of the ignorance that is in them, because of the hardness of their heart” (Eph. 4:18).
The true nature of life without God is now described in a series of devastating and depressing phrases. When one has no cognition of God, the old nature has both free reign and great power. Paul is not suggesting that everything listed here marks the life of all non-Christians, but he is indicating that this is the path that life tends to take without God. Without God, all else is vanity and without purpose.
A person without God may have much knowledge but they have no light of wisdom and thus they can be described as one whose understanding is darkened. It is sometimes hard for us to fully comprehend that one can be brilliant in the world’s eyes and still be darkened in the understanding of what is true and real about life. To know God is not simply knowledge about God but fellowship with Him, and thus one who chooses to live without knowing Him is excluded from the life that is only available in Him. It is tragic when one lives all of life without knowing his/her Creator and thus discovering one’s true purpose.
Man living without knowing God was never God’s desire but was caused by man’s hardness of heart. The word “hardness” is somewhat difficult to translate. It could be derived from a noun meaning “blind” or a verb that means to “petrify.” The meaning might combine the two. When one ignores the revelation God provides there is a subtle but sure hardening of the heart towards the things of God.
Don’t forget that Paul is reminding believers that they should no longer walk in “futility of mind” (17). When believers ignore God’s word, it can cause a hardening in our own lives concerning the things of God.
Prayer: Father, forgive me when I ignore Your truth and follow my own way. Amen.
