Matthew 5:Since Christ was crucified God has been building up the church of Christ while at the same time punishing the Jews. If that's "spending time", it's sure not quality time.
Christianity didn't evolve from Judaism. It is the antithesis of Judaism.
17 The Fulfillment of the Law.“Do not think that I have come to abolish the Law or the Prophets. I have come not to abolish but to fulfill them. 18 Amen, I say to you, until heaven and earth pass away, not a single letter,[e] not even a tiny portion of a letter, will disappear from the Law until all things have been accomplished. 19 Therefore, whoever breaks even one of the least of these commandments and teaches others to do the same will be considered least in the kingdom of heaven. But whoever observes these commandments and teaches them will be called great in the kingdom of heaven. 20 I tell you, if your righteousness does not exceed that of the scribes and Pharisees, you will never enter the kingdom of heaven.
