Martin Luther, in my devotional this morning:
The person who holds on to Jesus in faith will receive forgiveness of sins. God’s laws will be fulfilled, death will be conquered, and the devil will be overcome. That person will receive the gift of eternal life. For in this one man, Jesus, all is settled. He has fulfilled everything. Whoever accepts him has everything.
The key part is “who holds on to.” He came to fulfill the Law, yes, but apart from him, the Law continues to operate.
