Fundamentally, our faith is not about what we DO (as important as that is), nor is it about what we THINK (as important as that is). Our faith is fundamentally strengthened by understanding WHO WE ARE through the indwelling Christ.
We are who we are because of our union with Him. If we make what we DO (right actions) the place where our identity is located, then we become pharasaical, with the judgment of others’ misbehavior the preoccupation of our religion. If we make what we THINK (right doctrine) the place where our identity is located, then we become rationalistic debaters with judgment of others’ faulty doctrine the preoccupation of our religion.
Our identity is found in knowing and living out the fullness of Jesus Christ. Only then will his person and witness be the true preoccupations that fill our lives. Right doing and thinking are necessary for the proper filling, but Christ alone is the aim, the object, and the goal of what we do and think.
