Never reduce Christianity to a matter of demands and resolutions and willpower. It is a matter of what we love, what we delight in, what tastes good to us.
When Jesus came into the world humanity was split according to what they loved. The light came into the world and men loved darkness rather than light (John 3:19). The righteous and the wicked are separated by what they delight in—the revelation of God or the way of the world.
But someone may ask: How can I come to delight in the Word of God? My answer would be twofold: 1) pray for new taste buds on the tongue of your heart; 2) meditate on the staggering promises of God to his people.
The same psalmist who said How sweet are your words to my taste (Psalm 119:103), said earlier, Open my eyes that I may behold wondrous things out of your law (Psalm 119:18). He prayed because to have holy taste buds on the tongue of the heart is a gift of God. No man naturally hungers for and delights in Gods wisdom. Ask God to work this miracle in your life.
