1 Corinthians 8:11

And through thy knowledge shall the weak brother perish, for whom Christ died? (KJV)

Then: Explicitly back to knowledge, Paul adds a psychological, guilt reason for any believer to avoid being a stumbling block. Christ died for the sins of the one looking at another's example. This is a truth, a fact which will be heaped onto their souls. Were they the cause of another's slide away from salvation? It relates back to Jesus' teaching that it would be better for a millstone to be tied around the neck of him who caused a little one to sin than to come before the Lord's judgment for that action. Henry adds that he who has the Spirit of Christ will love those who love the Saviour so much that they too would die for those with weak consciences. In this regard what is the hold-up with only abandoning the practice of eating meat offered to idols?

Now: We cannot play with things of the spirit. Wonderful uncaring, Sunday morning worship; blythe, frothy attitudes of fellowshipping; superficial delights of service have no place in his kingdom. Depth and committment may produce joy in each act of service, but it's not etheral or purposeless. Bringing us to salvation was the Lord's plan of salvation so that we abide with love, faith and hope in him.
