The Sermon on the Mount are divine commandments for action in history insofar as they are the reality that has been fulfilled in Christ... Thus, the Sermon on the Mount itself confronts a person with the necessity of responsible historical action... The Sermon on the Mount is either valid as the word of God's world-reconciling love everywhere and at all times, or it is not really relevant for us at all.Bonhoeffer was critical of the idea that we can compartmentalize faith in Christ. The idea of saving Christian love and charity for Sunday and then embracing worldly pursuits and values the rest of the week is inconsistent with the teachings of Christ. Jesus teaches us this very thing in the Sermon. "The eye is the lamp to the body. So, if your eye is healthy, your whole body will be full of light; but if your eye is unhealthy, your whole body will be full of darkness. If then the light in you is darkness, how great the darkness! (Matthew 6:22-23)" You either live the Sermon on the Mount or you don't. You either live and believe what God has done and is doing through love and through Christ, or you don't.
"No one can serve two masters; for a slave will either hate the one and love the other, or be devoted to the one and despise the other. You cannot serve God and wealth (6:24)."
The Sermon on the Mount is truth about God's love for us through Christ. It is truth about the claim that God is making upon the world and its values. Followers of Christ seek to live their lives as a refection of God's truth that God's Kingdom is breaking in. Because it doesn't work to live out Christ's love only some of the time or to reflect his light only some of the time, our prayer is that God will guide us to always be true to his calling for us.
This is the point of the "Living Christ Love" guide. It is a reminder that being "the light of the world (5:14)" is not easy. But with the Spirit's help it is a spiritual pursuit that is worthwhile because it is based on love, on God, and on truth. Jesus teachings, when lived out, are freeing to your soul. "My yoke is easy and my burden is light (Matthew 11:30)." Living Christ's love, you can be true to yourself. You can be in relationship with others, even with difficult people. You can always be hopeful through faith and prayer. You can engage with others in a spirit of compassion and humility. You can disagree and not risk everything. You can be vulnerable and trust others. You can stay connected and not give up your true self; your true call.
Lord, teach us. He has in the "Sermon on the Mount" and has modeled what he taught through his life, his cross, and his resurrection. Help us, O Lord, to serve only you. Help us, within community, to be the light of the world so that others may come to know what God is doing right now as his Kingdom is breaking into the world.
Our Father in heaven,
hallowed be your name.
Your kingdom come.
Your will be done,
on earth as it is in heaven.
Give us this day our daily bread.
And forgive us our debts,
as we also have forgiven our debtors.
And do not bring us to the time of trial,
but rescue us from the evil one.
- Matthew 6:9-13
