Betrayal is unavoidable but God can use it in surprising ways and to our benefit. We've all been on the giving and receiving ends of betrayal. We can betray someone by both commission and omission. Betrayal isn't just the giving of information to a persons enemy or doing something to hurt someone. Betrayal includes hurting someone by not providing help when it's within our power to do so. This broader definition helps us see why none of us are innocent. Betrayal causes a huge divide but God is sovereign over it and intends to use it.
Betrayal is, by nature, a deeply personal offense. Betrayal can only happen in the context of close relationships. Casual acquaintances can't betray one another because they don't know enough or care enough about the other person. But the closer and longer the relationship, the more painful betrayal feels. The more you've walked with people through life or helped them wade through deep adversity, the deeper the betrayal will cut. This is what was sung by David, "Even my close friend in whom I trusted, who ate my bread, has lifted his heel against me."
But betrayal is never left unresolved for those who seek the face of God. A story can be twisted and a plot can be altered but God reserves the right to author the final chapters. Just following that first stanza from David he sings a new verse, "By this I know that you delight in me: my enemy will not shout in triumph over me." In the face of betrayal, David sings of his praise that God's face is not turned away. And not only that, the very ones who intended us harm will never have the joy of dancing on our grave. This is only true for one reason, "But you have upheld me because of my integrity, and set me in your presence forever." Much can be taken from you but a right relationship with God, built on the righteousness of Christ, can never be lost.
Do a "180 Now". Resolve to never betray a person ever again. When given the chance to be part of a gang-tackle, step away. When group-think runs rampant, ground your words in truth and love. If you have the power to aid someone in need, jump in. But what if you've been betrayed? Job one, come clean with God and ask him to guard your heart. Then hang on through the storm. Jesus gets it. And you don't need to be perfect like Jesus for God to hold you up. Just have the integrity to learn from anything and live to honor God in everything. You can do this! And the only trumpet that's gonna blow is the trumpet of God.
