Why does purity allow us to see God more clearly? Purity shows that our hearts are aligned with God’s heart. It’s an indicator of righteousness gained by grace through faith in Jesus Christ, and has no correlation to outward appearance. In fact, Jesus warns that religious people whose hearts are not aligned with God are like whitewashed tombs. To receive the blessing of seeing God more clearly, we must both receive (by grace through Christ’s sacrifice) and pursue purity in our lives.

Matthew 5:8
