The propitiation offered by the Lord Jesus showed that God’s righteousness was outside the law, and it was above the religious rituals. God justifies everyone who believes in the righteousness established by the Lord and not only those who only obey the dogma, and he will surely can gain the life of Jesus to eternal life. (Romans 3:21-25)

From this life to eternal life, those who follow the Lord can learn his life and enjoy the peace and joy of God the Father. The Lord Jesus told his disciples to have a new heart for the teachings he taught:

Cover or Remove

The disciples should not use his way as a patch of clothing to cover up their wrongdoing. No one will patch up old clothes with new cloth; because the patched back straps break the clothes, the clothes will be more damaged. (9:16)

The fasting and prayer of the disciples was to repent of their sins so that they could be forgiven by God, so that all injustices could be removed, not to cover and bury the sins in their hearts. (1 John 1:7-9)

They want to take off instead of covering the old man and the behavior of the old man, but put on the new man. This new man is gradually renewed in knowledge, just like the image of the Creator. (Col 3:9-10)

Imitate or Transform

Nor should he follow his teachings according to the old ideas in his heart. No one puts new wine in old leather bags; if this is the case, the leather bags will burst, the wine will leak out, and even the leather bags will be broken. Only by putting the new wine in a new leather bag, both are preserved. (9:17)

Wine in Jews’ thinking means the Word of God, and the Lord asks those who believe in him to receive his Word, and do not follow the practices and ideas of this world. The lusts of the flesh, the lusts of the eyes, and the pride of this life come from the world, none of which come from God the Father. (1 John 2:15-16, Romans 12:14-21)

Those who follow the Lord need to renew and change their minds and examine what God’s kind, pure, and pleasing will is, so that they can offer their bodies as living sacrifices to God, serve Him, and please Him. (Romans 12:1-13)
