Pastor Mark Willig preached an excellent sermon on being the fragrance from death to death this past year. Wish I had it so I could share it with you. If I recall correctly, it had to do with that as we preach - whether Law OR Gospel - we still stink of death to those who refuse to die to sin.
But more than that, I note "Who is sufficient for these things?" A question that has confronted me much lately as I have seen many of my failings of late. But that question was soon followed by the Gospel in the Responsory for Apostles (O-73) - I am not sufficient to speak, that is abundantly clear. But I have also been given the promise that His Word will be given to me by the Spirit of our Father - Matthew 10:19-20. Awesome
