Jesus calls us in Matthew 5:8 to be pure in heart. That seems impossible to me. Yet when God calls us, He equips us. First, in accepting Jesus and all He is and has done, He places His robe on me. A pure one.
We won’t experience personal purity until Heaven. Meanwhile, we pursue purity. We have a forgiven heart. God creates in us a clean heart, so we are free to keep taking steps forward pursuing God only. Acts 20: 24, "My only aim is to finish the race and complete the task the Lord Jesus has given me."
To be pure is to lay aside distractions, not be double-minded. Are you pulled in different directions? Ask God to give you a pure heart, single-mindedness. He promises to answer this prayer.
“Every pastor needs to read this book, and every church needs copies of this book available. Written by a widow, written for widows, this book reads like the experience of sitting at a coffee table watching one widow minister to another widow. It’s that personal. And because there are so many widows, it’s that important.” - Scot McKnight - Karl A. Olsson Professor in Religious Studies, North Park University, Chicago.
