"Can the wedding guests fast while the bridegroom is with them?"

Scripture: Mark 2:18-22
The disciples of John the Baptist were upset with Jesus' disciples because they did not fast. Fasting was one of the three most important religious duties, along with prayer and almsgiving. Jesus gave a simple explanation. There's a time for fasting and a time for feasting (or celebrating). To walk as a disciple with Jesus is to experience a whole new joy of relationship akin to the joy of the wedding party in celebrating with the groom and bride their wedding bliss. But there also comes a time when the Lord's disciples must bear the cross of affliction and purification. For the disciple there is both a time for rejoicing in the Lord's presence and celebrating his goodness and a time for seeking the Lord with humility and fasting and for mourning over sin.
Jesus goes on to warn his disciples about the problem of the "closed mind" that refuses to learn new things. Jesus used an image familiar to his audience — new and old wineskins.The Lord gives us wisdom so we can make the best use of both the old and the new. He doesn't want us to hold rigidly to the past and to be resistant to the new work of his Holy Spirit in our lives. He wants our minds and hearts to be like new wine skins — open and ready to receive the new wine of the Holy Spirit.
