As our resurrected Lord, Jesus the Man as the second Adam, is the “first fruit” of New Creation. Christ in Himself is the Life and the Resurrection that we share in when we are joined to Him by the Spirit. We died with Him and we have been resurrected in Him. His Life is our life. His death is our death and His resurrection is our resurrection. So, as New Creations ourselves now in Him, we are the proof of Jesus’ Resurrection! We are the proof that He is alive and active because the Church as His Body is His life and activity in the world. We are the very presence of Christ on earth.
Our challenge as Christians, then, is to manifest His Life by living into our identity as sons in the Son. Our only obligation as Christians, as sons and daughters of God in Christ, is to live out His life that is in us. In other words, our obligation of obedience is be who we are—the presence and fragrance of Christ! How? Not by following a bunch of rules or by “keeping the Law” or by being the doctrinal police, but by living lives of Love in the power of the Spirit! As Children of the living God, as those who have been united to God in Christ through the Spirit, love is the only measure of our lives.
For Paul the only thing that mattered is the New Creation; which is to say, Faith working through Love. And the love that we exercise toward one another and the world is the proof of the Resurrection because love is the proof of Christ in us.
So the question we should be asking ourselves is not, Do we have all our “doctrinal ducks” lined up correctly? No. The question is: What does the world see when they look at us? Do they see love? If so, then (and only then) will they see Jesus—as He said they would.
As “New Creations” in Christ, as those who share in Jesus’ Resurrected Life and thus participate in the very life of God Himself (the life of the Father, Son and Spirit that is love), our calling is simple: we are to be who we are—by living lives of love.
