I have been playing the guitar for more than 20 years, and I have callouses on my fingertips. When I started playing the guitar, the pain was terrible, but now I can play without feeling anything.
The same things happens with our conscience. When we begin to break God's law, we feel terrible. For example, the first time you lied to your parents or the first time you had sex outside of marriage. But as we continue to sin, we develop callouses on our conscience to the point that we do not feel any guilt at all.
When we die we will have to give an account of our lives to God and there will not be any way to justify our disobedience or our sin. An eternity full of shame and guilt awaits us.
Jesus Christ came to this world to forgive your sins. He was perfect in everything and never allowed his conscience to develop callouses. He gave up his life on the cross to take away the sin in your life. Call out to him for forgiveness today and put all of your trust in him. Surrender your life to Jesus and allow him to remove all of your guilt.
