Hope is the feeling that what is desired is possible and that events may turn out for the best. Or so says the dictionary. But the biblical concept of hope is far beyond this dim and sketchy definition of hope. The hope the Bible speaks of is robust and hearty, being rooted in putting our hope in the Word of God.
I wait for the Lord, my soul waits, and in His Word I put my hope.
In the great eighth chapter of Romans, which is the solution to St. Paul's wrestling with his sin in chapter seven, we see a profound truth. It is that those who live according to the flesh and are controlled by its unholy desires, set their minds on and pursue those things which gratify the flesh. But those who are according to the Spirit and are controlled by the desires of the Spirit, set their minds on and seek those things which gratify the Holy Spirit. So the life of the Spirit requires a mind change.
