Faith is how union with Christ becomes operative and powerful in your life. Faith is a God-given gift that allows you to take hold of God’s having taken hold of you.
If you are in Christ, this is now the defining truth of who you are. Your life, your story, becomes enfolded by another story. That’s one way to define faith: faith means finding your identity in Christ. “I live by faith in the Son of God, who loved me and gave himself for me.”
Paul is unusually personal here because he wants it to be utterly personal for you. He wants you, too, to be able to say, “I live by faith in the Son of God, who loved me and gave himself for me.”
Belive in Christ
My core beliefs were that I was not worthy, accepted, or loved, so I would clamor and manufacture ways to elicit the positive responses I wanted from people.
This is another way to picture what it means for you to be in Christ. You are completely safe, hidden in him. He represents you before the Father. He covers you—your sin, your shame, your weakness. But he covers you in a very real way, not as a temporary fiction.
But being in Christ is to discover our true, God-given identity. You are alive in him, moving with him through this world, clothed in all his benefits and blessings. You are in Christ.
To be found in Christ means you don’t have to prove yourself anymore. Your frantic attempts to find or craft an acceptable identity, or your tireless work to manage your own reputation. You don’t have to be intimidated by anyone, ever. You no longer need to fear the judgement of God (1 John 4:18). When God looks at you, he sees you hidden in Christ. This is freedom, confidence. Which is good news.
