I purchased this as an anniversary gift for my husband (eight years) to help us commit to praying intentionally together daily. We pray separately throughout the day, and at the evening meal with our kids, but I wanted something that was just for us. Now we'll have developed a habit of prayer together to build our faith and draw us closer to each other and Christ, and also be able to look back over the next few years and see what was happening in our lives, which will build up more reasons to thank God for His faithfulness and remind us of how far we've come together. I would absolutely recommend this to anyone seeking a more consistent prayer life; the applications are innumerable. It could be a gift to a child, a friend, for yourself, a newer Christian at your church; something you could fill with prayers for your pastor and later gift to him to show how you've supported him in prayer daily for years; prayers for hopes and dreams or through intense struggles; prayers for your marriage; prayers for missionaries; prayers for a business startup.... Or whatever is on your heart. It was made to be used, to be treasured. There could be "One Thing" you ask, or many. May it - however you choose to use it - bolster your faith in the God who hears and answers the prayers of His loved ones!
