I have a rule in my Bible study: during group prayer, before anyone can pray for local concerns (Fred’s mother, Jill’s uni exams, etc.) they need to either give thanks for something or pray for something beyond our group.
Mark Altrogge has food for thought on that list of things to give thanks for:
God’s mercies are all around us. But do we notice them?
A good exercise is to write down God’s mercies.
Some folks write down something they’re thankful for every day. Before you start asking God for things, consider thanking him. Enter his gates with thanksgiving and his courts with praise.
