Surely the greatest social injustice is that 2 billion people haven't heard of God's love in Christ.

No matter how many red Xs we write on our hands to end slavery, as long as these same hands are clicking on pornographic websites and scrolling through sexual pictures and videos, we are frauds to the core.

This is the gospel. The just and loving Creator of the universe has looked upon hopelessly sinful people and sent His Son, God in the flesh, to bear His wrath against sin on the cross and to show His power over sin in the resurrection so that all who trust in Him will be reconciled to God forever.

God involves us in his mission not because he needs us but because he loves us.

So the challenge for us is to live in such a way that we are radically dependent on and desperate for the power that only God can provide.

Do you believe that Jesus is worth abandoning everything for? Do you believe him enough to obey him and to follow him wherever he leads, even when the crowds in our culture - maybe even our churches - turn the other way?

We are settling for a Christianity that revolves around catering to ourselves when the central message of Christianity is actually about abandoning ourselves.
