“What you need to drive out an old passion, is a new passion, a greater passion. What you need is an over-mastering positive passion. [...] Just as Rachel was Jacob's over-mastering passion, the passion of his life, Jesus is our "Rachel". To the degree, that you see Jesus on the cross, loosing absolutely everything for you, He will become a beauty to you, He will become so beautiful in your eyes that you'll be able to change these things that control
you now, they'll loose their power.
Do you know how to work on your heart like that? It's only by rejoicing in and resting in what Jesus Christ has done for you. Then you can replace your idols. And if you really want to change and want to pound the Gospel more deeply into your heart - Jesus Christ must become your over-mastering positive passion.”

“It is the most sweet and comfortable knowledge; to be studying Jesus Christ, what is it but to be digging among all the veins and springs of comfort? And the deeper you dig, the more do these springs flow upon you. How are hearts ravished with the discoveries of Christ in the gospel? what ecstasies, meltings, transports, do gracious souls meet there? Doubtless, Philip’s ecstasy, John 1: 25. 'eurekamen Iesoun,' 'We have found Jesus,' was far beyond that of Archimedes. A believer could sit from morning to night, to hear discourses of Christ; 'His mouth is most sweet', Cant. [i.e., Song of Solomon] 5: 16.”

“The gospel, if it is really believed, removes neediness - the need to be constantly respected, appreciated, and well regarded; the need to have everything in your life go well; the need to have power over others. All of these great, deep needs continue to control you only because the concept of the glorious God delighting in you with all His being is just that - a concept and nothing more. Our hearts don't believe it, so they operate in default mode. Paul is saying that if you want to really change, you must let the gospel teach you - that is to train, discipline, coach you - over a period of time. You must let the gospel argue with you. You must let the gospel sink down deeply into your heart, until it changes your motivation and views and attitudes.”

“There are only two ways that God’s justice can be satisfied with respect to your sin. Either you satisfy it or Christ satisfies it. You can satisfy it by being banished from God’s presence forever. Or you can accept the satisfaction that Jesus Christ has made.”
