The passions we choose in life determine our level of contentment. If we give ourselves to some things, we will surely wind up devoid of satisfaction. Chasing after godliness will give us a lasting contentment that cannot be taken from us.
Revelation tells us about the unfolding story of God's grace and Christ's sacrifice so that we can be forgiven and know how to love a fallen world. Christ's resurrection is the proof and pledge that God intends to make all things new.
