Matthew 9:14-17, "John's followers came and asked Jesus, 'How is it that we and the Pharisees fast, but Your disciples do not fast?' "
(The disciples' fasting was a sign of mourning for sin and to prepare for the Messiah's coming. They didn't need to fast for Jesus WAS the Messiah.)
"Jesus answered, 'How can guests of the bridegroom mourn while he is with them?'"
(The arrival of the kingdom of heaven is like a wedding feast with Jesus as the Bridegroom, therefore the disciples were filled with joy!)
"This time will come when the Bridegroom will be taken from them; then they will fast."
(When Christ died on the cross for mankind's sins, the disciples realized this.)
"No one sews a patch of unshrunk cloth on an old garment, for the patch will pull away from the garment making the tear worse."
(Jesus did not come to patch up the old religious system with its rules and regulations. He brought something new though it had been prophesied for centuries. That being Jesus reconciling man to GOD through His sacrifice on the Cross for mankind's sins. We must be prepared to live the new life in Christ.)
"Neither do men pour new wine into old wine skins. If they do, the skins will burst, the wine will run out and the wine skins will be ruined. No, new wine is poured into new wine skins and both will be preserved."
When you accept Christ as your Savior you are admitting He paid the penalty for your sin and you become a NEW person. You are preserved in His Holy Spirit to do good works bringing others to His saving grace.
