The inner essence of worship is cherishing Christ as gain - indeed as more gain than all that life can offer - family, career, retirement, fame, food, friends. The essence of worship is experiencing Christ as gain. Or to use words that we love to use around here: it is savoring Christ, treasuring Christ, being satisfied with Christ.
John PiperI've never heard anyone say the really deep lessons of life have come in times of ease and comfort. But, I have heard many saints say every significant advance I've ever made in grasping in the depth of God's love and growing deep with Him, have come through suffering.
John PiperWhen the heart no longer feels the truth of hell, the gospel passes from good news to simply news
