The Bible teaches that Christ fulfilled the Law through His perfect life and death on the cross. But what about how the feast of weeks, which is itself described in the Law, was fulfilled later at the point of Pentecost (in Acts 2)? Is it correct to say that the Law was fulfilled in its entirety at the cross, or were/are other parts fulfilled later?
As you correctly point out, the Law is fulfilled in Christ. Christ Himself puts it this way:
Jesus says He will fulfill all the Law, which began with His perfectly obedient life and His sacrificial death:
But notice Jesus also said that His accomplishment of the whole Law will not be complete until heaven and earth pass away, which refers to the end of the millennial kingdom. Jesus is referring to the Law’s promises to Israel as a nation, which are to be fulfilled during the 1,000-year kingdom. So while Christ fulfilled the Law’s requirement for an obedient life and an atoning sacrificer sin during His first coming, the fulfillment of the Law’s promises to Israel in the Kingdom await Christ’s Second Coming and His reigning on earth.
