Jesus speaks so often about the difference between head-knowledge and heart-knowledge, of obedience for the sake of the Law, and willing obedience for the sake of Jesus.
Christianity is not a list of rules to follow in order to earn God’s favor. It’s a changed heart that is the result of repenting of sin and accepting the forgiveness God provides through Jesus. It’s a changed heart that wants to obey God out of love and appreciation for having received God’s favor at the cross. It’s willing obedience in light of God’s grace.
Oh, for changed hearts, not just people who do good things, or go to church, or simply wear His Name.
It’s what God demands. And it’s exactly what our world needs.
