The next Christian mindfulness exercise is the hardest: Carry on a conversation with God and try to make it continual.
The Christian best known for doing this is Brother Lawrence, who died on February 12, 1691. He served as a lay brother in a Carmelite monastery in Paris, typically working in the kitchen. He never achieved prominence during his life, and yet he is remembered today more than any other Christian of his time.
Brother Lawrence developed an intimate, continual conversation with the Lord. He became known when his letters and writings were compiled into a book called “The Practice of the Presence of God” after his death. You can find a free PDF of the book here.
The Carmelites of Boston website sums up his teachings like this:
Speaking humbly and lovingly with Him (God) all the time, at every moment, especially during times of temptation, suffering, aridity, weariness, even infidelity and sin. This habit is formed by repetition of acts and frequently bringing the mind back into God’s presence … conversing with God everywhere, asking Him for what is needed, and rejoicing continuously with Him in countless ways.”
Paul would agree. As he wrote in Philippians 4:4-7: Rejoice in the Lord always. I will say it again: Rejoice! Let your gentleness be evident to all. The Lord is near. Do not be anxious about anything, but in every situation, by prayer and petition, present your requests to God. And the peace of God, which transcends all understand, will guard your hearts and minds in Christ Jesus.”
