The use of "Amen" at the end reinforces the sincerity and finality of the prayer. Here are some possible rephrasing options: 1. "May we be guided by God's grace and wisdom in this new day and week. Amen." 2. "Let God's grace and wisdom lead us as we begin this new day and week. Amen." 3. "As we start this new day and week, may God's grace and wisdom go ahead of us. Amen."
