Almost all of us have parts of our lives we really want to see changed, but change is really hard. And it’s very possible to mistake a morally restrained heart for a supernaturally changed heart.

If you squeeze a rubber ball and then take your hand away, it snaps right back to where it was. You restrained the rubber ball temporarily, but you didn’t really change it. Almost all of us have that rubber ball experience. We try to change parts of our lives, and we put a lot of willpower behind it. Then as soon as circumstances change, it snaps right back.

1 Corinthians 13 tells us that a supernaturally changed heart 1) is not the same as a busy life in service of others, 2) is not the same as a morally committed life, but 3) is meeting love as a power and as a person.

We’ve lost connection with part of what the Bible teaches about sin: that God gets angry at sin. And I’m here to tell you that losing that is a bad thing.

In fact, I’ll go this far: you need an angry God. If you don’t believe in an angry God, a really angry God who hates sin and is going to punish it, you’re impoverishing yourself. You’re taking away all sorts of hope and humility and love.

Isaiah 64 and 65 show us 1) God’s anger is not like our anger usually is, 2) you need an angry God if you’re going to live in hope, 3) you need an angry God if you’re going to live in humility, and 4) you need an angry God if you’re going to understand how loved you are.
