"The things which are seen are temporal; but the things which are not seen are eternal" (2 Corinthians 4:18)
Indeed it may be truthfully said that everything of lasting value in the Christian life is unseen and eternal. Things seen are of little real significance in the light of God's presence. He pays small attention to the beauty of a woman or the strength of a man. With Him the heart is all that matters. The rest of the life comes into notice only because it represents the dwelling place of the inner eternal being.
The solution to life's problems is spiritual because the essence of life is spiritual. it is astonishing how many difficulties clear up without any effort when the inner life gets straightened out.
If half the time we spend trying to fix up outward things were spent in getting our hearts right, we would be delighted with the result.
Christ will not dwell in our hearts, if we fill our hearts with thing which He hates. To do willfully and knowingly what God hates, destroys faith, and hope, and love.
