Determination of will. This is where we resolve to believe God's Truth and follow it. This means putting to death sin and wickedness and putting on Christ and His righteousness. The Christian is resolved, come what will, heaven will be had. Vitality and fervor of affection.
Affections are violent things in and of themselves.
My soul thirsts for God, for the living God. Yesterday when I was having lunch at work I mentioned to a Christian fellow-worker that the Christian artist Rich Mullins had died in a car crash. That is an understanding of and affection for heaven. Strength to persevere. It is easy to talk about Truth, but it is not so easy to know Truth and apply it to our lives.
