Human love is shaky. It’s weak and wavering, soft and unreliable. As David discovered yesterday, the best of friends can quickly become the worst of enemies. Our best buddy can become the worst betrayer, as most High School students can testify. So much of the teen depression and anxiety epidemic is spread through the unfaithfulness and unreliability of friends. Shaky friendships produce shaky hearts. Is there a steady love that can give us steady hearts? David answers that question in Psalm 57.
