What is the benefit of giving thanks? 1 Thessalonians 5:18 says that giving thanks “is the will of God concerning you.” When you give thanks, you are in the will of God. When you are grumbling, you are outside of God’s will. To give thanks is to position yourself smack-dab in the middle of God’s will. This is critical because “We know that God causes all things to work together for good to those who love God, to those who are called according to His purpose.” (Romans8:28)
