I eliminated those passages that did not deal with that and came up with this list.
Looking at those verses it looks to me like in order to fulfill the law of Christ we need to:
- Love our neighbor as ourselves (that is mentioned 4 times)
- Bear one another’s burdens (which would seem to be a corollary to the one above)
- Walk according to the Spirit (which would be the only way that we could do the other two)
He bore our burden of sin on the cross. He did that as Romans 5 tells us while we were ungodly, sinners, enemies, and strangers.
He did not do any of this apart from what His Father told Him to do – essentially walking according to the Spirit.
To me that seems to be a fairly fully-orbed description of what it means to fulfill Christ’s law. What do you think.
