Thomas Watson on Sanctification

"The main thing a Christian should look after is sanctification. This is the unum necessarium, 'the one thing needful.' Sanctification is our purest complexion, it makes us as the heaven, bespangled with stars; it is our nobility, by it we are born of God, and partake of the divine nature; it is our riches, therefore compared to rows of jewels, and chains of gold (Song of Solomon 1:10). It is our best certificate for heaven. What evidence have we else to show? Have we knowledge? So has the devil. Do we profess religion? Satan often appears in Samuel's mantle, and transforms himself into an angel of light. But our certificate for heaven is sanctification. Sanctification is the firstfruits of the Spirit; the only coin that will pass current in the other world. Sanctification is the evidence of God's love. We cannot know God's love by giving us health, riches, success; but by drawing his image of sanctification on us by the pencil of the Holy Ghost it is known." (from "A Body of Divinity" by Thomas Watson")

Thinking upon this quote caues me to contemplate upon that evidence of God's love (sanctification) and whether it is being manifested in my life.
