Jesus had lingered a few days before answering Martha and Mary’s summons to help their dying brother. When Jesus arrived, Martha offered a stinging statement of faith: If you’d been here, Lazarus wouldn’t have died. Jesus brought Martha to deeper faith by revealing that he is the resurrection and the life.
Perhaps your faith needs a Martha transformation from If you had only done this … to Yes, Lord, I believe. When God seems to tarry, rather than saying If only, try, I believe. He is the resurrection and the life. His plans often involve greater works (like raising the dead) than you can imagine.
