If God was really in us, we might discover some amazing things such as: how much like Jesus we are, that false doctrine is anything that teaches us to assume He is is not in us, that most of our confusion is the result of holding on to thoughts that deny His really being in us, that our attempts at humility are built upon a rejection of Him being in us, and that our attempts to dedicate or rededicate ourselves to God are an outright rejection of Him having dedicated us to Himself once for all time.
How can you realize the freedom you have in Christ? I say that you will discover it, more times than not, in the midst of the bondage that still seems to hold you down. You see, the power of the gospel is not found merely in the words of its testimony of Jesus’ death and resurrection, it is found in the reality that has been brought about because of who he is and what he has done. That reality is that Christ is in you. He is there, and his life witnesses from within you … despite all the doubts that you think actually come from within you. source
