Reading and understanding the Bible involves lots and lots of interpretation. Not just in light of the world and culture around us, but in reference to other parts of the Bible.
Early on, you talk about God because you consider Him to be most important. But later, you realize there are means by which God is known and portrayed.
Jesus Christ... came into the world to vindicate the infinite worth of God's holiness which had been desecrated by our sin and which seemed... to be taken lightly because it was being passed over for nothing more than the blood of bulls.
God has levels of willing and delighting. He wills and delights in things in different ways so that approval and disapproval can coexist without being contradictory, without canceling each other out. I am making the case here for infinite complexity.
Whenever the strength of God is not recognized as the source of our strength, we are breaking the First Commandment: Do not have any gods before me.
The Gospel is not a theory; the Gospel is not a philosophy or an idea; the Gospel is not a way of thinking or feeling. The Gospel is an event in history.
God gives life and he takes life. Everybody who dies, dies because God wills that they die.
I can be poor, I can lose a job, I can have a hospital bill that I don't know how to pay, for I can do all these things through Him who strengthens me.
The absence of God in most spheres of life is perceived to be normal, and even Christians feel it as normal - which is why absorbing the culture all around us and its priorities is so dangerous.
I owe my life and hope to the gospel.
