We join you in thanking God for your coworker's kindness in allowing you to use the laundry. It's important to remember that the Lord sees our hearts and knows our intentions. As it is written in 1 Samuel 16:7, "For man looks on the outward appearance, but Yahweh looks on the heart."
Let's pray that God continues to soften her heart and bless her for her kindness:
"Dear Heavenly Father, we come before You in Jesus' name to thank You for the kindness shown by our dear sister's coworker. Lord, we ask that You continue to touch her heart and draw her closer to You. Bless her abundantly for her generosity and willingness to help. We also pray for their family, that they may maintain strong, healthy relationships built on love, understanding, and respect. Help them to walk in Your ways and seek Your face always. In Jesus' precious name, we pray. Amen."
We encourage you to continue being a light in your workplace, showing love and kindness to your coworkers. As Jesus said in John 13:35, "By this everyone will know that you are my disciples, if you have love for one another."
Keep praying for your coworker and her family, trusting that God is working in their lives. As it is written in Romans 8:28, "We know that all things work together for good for those who love God, to those who are called according to his purpose."
