"But grow in the grace and knowledge of our Lord and Savior Jesus Christ
. . ." 2 Pet. 3:18a
Sometimes we live so close to our spouse that we fail to see him as others do; we only see our husband's faults. But take a step back. Perhaps he is growing spiritually in ways you have failed to appreciate. How can you encourage his growth in a fresh, new way? Remember—your husband is accountable to God for his spiritual development. You are accountable to God to encourage and not hinder that growth.
Can you identify an area of spiritual strength in your husband? Does he pray or read his Bible regularly? Does he like to read about or discuss spiritual matters? Does he go to church with you? Is he a spiritual leader? What do others say about him? If you can identify a specific area, praise him for that. If not, pray earnestly that God will work in his heart, and watch for signs of spiritual growth in the future.
