In this chapter, John Piper compares faith in future grace with pride.
Pride is the essence of unbelief. Piper compares faith with pride and connects unbelief and pride. Unbelief is when we turn from God and believe or find satisfaction in something else. Pride is when we turn from God and believe in self.
We get anxious about the future and become self-sufficient, so we do try to do things by our own strength. Pride says we can boast in our achievements and don't need God in our lives.
Probably something I've never thought about was how self-pity could also be a form of pride. Self-pity is a form of self-exaltation and says "look at me, I've suffered so much and deserve recognition".
I suppose it's really easy to fall into the sin of pride. It's an ever important reminder to ourselves, that everything belongs to God. He gave us intelligence, strength, talents which without him we are nothing.
Yet there is another spectrum to avoid - false humility or self-pity. May our only boast be in Christ alone. He must increase, and I decrease.
Jeremiah 9:23-24 ESV
Thus says the Lord : “Let not the wise man boast in his wisdom, let not the mighty man boast in his might, let not the rich man boast in his riches, but let him who boasts boast in this, that he understands and knows me, that I am the Lord who practices steadfast love, justice, and righteousness in the earth. For in these things I delight, declares the Lord .”
