What does it look like to address an issue of the affections by exposure to the attractiveness of our Lord, rather than by effort of the flesh?
Perhaps the marriage analogy can help here. If I am growing cold in my affections toward my wife (which, if she reads this, I am not!), then the solution is not to “do the right thing.” I can go and buy flowers and give them to her and even say “I love you” through clenched teeth. That doesn’t do much for me, and does even less for her. I am much better off simply being with her, allowing her attractiveness to draw my affections to her again. That is what I’m suggesting spiritually – allow the love of God to draw you to Him.
One last suggestion that has helped me was given to me by a good friend several years ago. I pass it on to you gladly. If I don’t feel like reading the Bible and being exposed to the attractive beauty of God’s grace, I don’t pretend otherwise and force myself, I tell him so. “Lord, I don’t feel like reading your Word today. Other things are far more interesting and attractive to me…” Praying honestly (and out loud!) tends to bring conviction and brokenness as the Spirit of God works in my heart. Before long I am broken at the foot of the cross, overwhelmed by the grace of God to a sinner like me. Before long I want to be in His Word, not as an external duty, but with a captured heart, strangely warmed, but never proud of my own effort!
