Blind spots can keep us from spiritual growth. These can be things we simply haven't learned/seen yet. Not focusing on the whole picture can also skew our spiritual vision. Most deadly of all is when we are in a state of denial about the seriousness of our sin. In all cases, the challenge is that we don't see blind spots, hence the name. If we are examining the scripture with humility and not shying away from correction that comes our way, and praying for God to show us what we need to see, we can overcome.
