My flesh and my heart may fail, but God is the strength of my heart and my portion forever. (Psalms 73:26, NIV 1984).
My Musings – They will fail. But unless there is an end to forever, God will not.
My Advice – “And if [God] never lasts forever, tell me, What’s forever for?” (What’s Forever For, Michael Martin Murphey). When the time comes that your flesh and heart fail, and it will, you can know what forever is for. If you know Jesus.
