The “heart” referred to in the Bible is not the organ that pumps blood around your body. Rather, it is a reference to the real you that cannot be seen – the center of your being, your true essence, which is your spirit.

Men and women are in a state of symbolic darkness before they are saved and Christ has entered into their spirits. Technically, unsaved people are spiritually asleep, and saved people are spiritually awake.

Jesus is our spiritual sun, and the absence of the spiritual light of Jesus equates to spiritual blindness. Satan has blinded the minds of unsaved people, which explains their inability to see and understand spiritually.

God has given us free will, and we have the choice to either choose to walk in Satan’s darkness, or Jesus’s light. God will not force the light down anyone’s throat.
