Still working out what I feel about the doctrine of sanctification (leaning toward it being a long-term, life-long, most likely unattainable, but still worth striving for, goal), but think this is a rather good checklist:

When John Wesley was asked, ‘But what good works are those, the practice of which you affirm to be necessary for sanctification?’ he replied, ‘First, all works of piety such as public prayer, family prayer and praying in our closet, receiving the Supper of the Lord, searching the Scriptures, by hearing, reading, meditating, and using such a measure of fasting or abstinence as our body allows… Secondly, all works of mercy, whether they relate to the bodies or souls of men, such as feeding the hungry, clothing the naked, entertaining the stranger, visiting those that are in prison, or sick, or variously afflicted, such as endeavoring to instruct the ignorant, to awaken the stupid sinner, to quicken the lukewarm, to comfort the feeble-minded, to succor the tempted, or contribute in any manner to the saving of souls from death. This is the way wherein God hath appointed his children to await for complete salvation.’

(John Punshom’s Reasons for Hope)

I’d add that all of the above should be done in love and with a joyful and thankful heart. I also wonder about the man who gives his life for his brother’s or refuses to deny Christ at any cost.

Revelation 7:14 I said to him, “Sir, you know.” And he said to me, “These are the ones coming out of the great tribulation. They have washed their robes and made them white in the blood of the Lamb”
