Mary didn’t know who she was without Jesus. But, when she focused on who she was with Jesus, everything changed. Being aware of whose she was, and who she was, gave her vision for her life, and her mission to the disciples (and the rest of us).
Jesus' work on the cross may be finished, but His work in us is just beginning. All of us have doubts about a vision for the future. Jesus reveals God’s grace to cancel our doubts. We must have faith in order to see what is unseen and He will reveal where He would have us go next.
