Jesus is Truth. But we cannot fully experience the fullness of Truth if we only show up on Easter Sunday, dressed in our finest. We must first let Truth lead us on a journey with Him. For there is no power in resurrection without the wine, the bread, the cross and the tomb.
The purpose of giving something up for Lent is to ask God to draw you closer to Him as we, the body of Christ, draw closer to the foot of the cross. Lent is not a law, but an opportunity.
