Jesus said to them, “If you were blind, you would have no guilt; but now that you say, ‘We see,’ your guilt remains."
Sometimes truth is revealed very gradually, and lately one that has become more and more self evident is this dangerous little notion: Ideas have consequences.
God has given us the capacity for ideas and a means with which to communicate them and conversely enabled in us creativity, imagination, and the ability to dream and hope for the future. However, we started having the wrong ideas.
We started trusting in our own ideas rather than those of God. Our own perceptions have taken over and our vision of reality is distorted. The more we say that "we see", the blinder we become. We have given up God's vision for our own selfish and blind ambition. And this is judgment: that those who were blind now see and those who claim to see become blind (v39). God has blinded the hearts of men lest they turn and be healed (Isa 6:9-10) in his judgment.
But praise God now that the Truth has been revealed to us, God in Christ, so that all who look upon him and believe be saved (v37-38). No longer do our hearts sit blindly in judgment, but we have been shown our sin. There is, now, therefore, no excuse for anyone to not be in Christ unless their eyes are still blinded by God. Yet, Christ is being made manifest by his Church so that no man may have an excuse to be condemned.
