I've been very blessed by stumbling across the sermons of Victor Shepherd on the web.
Here's a thought of his prompted by Revelation 5:5:
Then one of the elders said to me, "Do not weep! See, the Lion of the tribe of Judah, the Root of David, has triumphed."
Here's what Shepherd says:
I think that what a pastor must have above everything else is a conviction concerning Christ's victory; a conviction so deep in him that it goes all the way down to his DNA, and he exhales it upon his people both explicitly and implicitly even as it seeps out of every pore. A pastor has to be convinced unshakeably of Christ's victory if he's profoundly to support and sustain his people.
