The Collect for Lent IV, the Epistle from Galatians 4:21-31, and the Gospel from John 6:1-13 all provide contrasts between the natural human condition and the human condition under divine grace. The Collect prays for grace and comfort despite our evil. Galatians 4 notes the difference between two covenants. This is the distinction between being children of bondage with legalistic considerations and being children of the divine promise, born anew to freedom through the Holy Spirit. The Gospel from John 6 is the familiar miracle of Jesus feeding the 5000. On the literal level, the miracle shows how Jesus uses His power to care for the hunger of those who have come to hear Him teach. However, especially in John's Gospel, such physical miracles point beyond themselves and are also signs of spiritual truths. As the context in John indicates, Jesus can also feed higher and deeper human hunger with His words and with Himself.
Thus, the theme of this Sunday can be summarized as a contrast between the fallen human condition in the world and the redeeming power of God's grace. This theme is always important for people to hear and keep in mind, but it has a special relevance to those who are observing Lent. As Christians prepare to appreciate Easter, the Church historically emphasizes good disciplined behavior. Every human being needs to hear that emphasis. We need to be reminded of God's Law and our needs, especially the need to repent.
Unfortunately, we humans have a natural tendency to get too caught up in the externals. We tend to focus on commandments, specific actions, and physical needs more than we do on divine grace, spiritual perspectives, and the good news of redemption through Christ. So as we continue through Lent, let us not be overly legalistic; rather, let us view our self-discipline in light of divine grace and focus on the redemptive message of the Gospel.
