And whose minds are in the dark. They have no part in the life that God gives, for they are completely ignorant and stubborn. Ephesians 4:18
Every man has a purpose in Christ, but many times he is limited by his condition, which makes him remain in ignorance. Then years go by without results, which shows that he is not doing what God has commended him to do.
This knowledge is not learned at universities, schools or training programs. That is why, no matter how much we have studied, if we do not have revelation, we are left in ignorance. It can be voluntary or involuntary. Voluntary is when we know that we have to do it, but we do not; involuntary is the one where one has total ignorance, until the Holy Spirit reveals it to us, and it is not so anymore.
That is why there are many who do not advance. They are left behind on the road, that is Christ, because they are insensitive at heart. This does not allow them to seek the presence of God, so the eyes of understanding can be open for them. This way, they may understand their purpose and walk toward it. In such cases, it is evident that we remain the same, for we have not given this the value it has for our lives because we consider what we know is enough and there is nothing else to learn.
