Here is the story of a college student who ignored the need to daily cleanse her contact lenses. After six months of ignoring this fact, she found that amoebas had eaten her eyeballs and left her blind.
How could she let this happen? Didn’t she notice anything changing? Didn’t it hurt or at the very least, didn’t she notice the change in her vision?
After thinking about this I can see the parallels to sin. When we don’t deal with the sin in our heart by taking it to Christ, it begins to gnaw, slowly consuming us. After a while we are no longer bothered by our conscience and we have so grieved the Holy Spirit that we no longer sense the danger we are in.
Deal with your sin daily. Ignoring it can lead to spiritual blindness and further consequences.
