God always shows up at the time we least expect and that is in His own time. He works according to time and not according to circumstance like you said. God works according to his own time not our time, this we must understand. Often times we allow our circumstances distract us from recognising the power of God that is able to do the impossible in our life. Mary was moved by the fact that there was no wine and people were complaining, it was not the right time for Jesus to act. We shouldn't push God to act rather we should wait patiently for His perfect time. Thanks for this message
