What does it mean to be holy? The Bible talks a lot about holiness, and it can be a confusing concept. Holy means “set apart.” That meant something distinct in ancient Israel. The temple was designed with increasing levels of holiness, or set apartness. God’s people are set apart from other people in the Old Testament and are supposed to remain separate. But Jesus changes that. Hebrews 10:10 tells us that we are made holy by Jesus - that’s how we are set apart. It’s a lot different than the Old Testament. It’s less precise, harder to measure. Still, God’s people are set apart. Before Jesus, the set apartness was marked by following the rules. But now we are set apart by something else. As we continue in Ephesians this week, Paul is going to talk about what he calls “true holiness” and give some concrete examples of what it looks like. It’s an important word for the church in the 21st century.
