Fasting is extremely beneficial to our spiritual growth and our prayer lives. Going without food helps reminds us how much we depend on God for our sustenance and, indeed, for all things. This helps us seek Him fervently, for we know that the only hope we have to see our loved ones saved and our lives changed is through His working. Consider taking some time to fast and pray this week so that you may know what it means to rely wholly on the Lord.
