When we have hardened our hearts, it’s difficult if nearly impossible for God’s Word to penetrate that tough exterior. In Acts 28:27, Paul used the term “calloused hearts” when dealing with the unbelieving Jews in Rome as he quoted Isaiah 6:9-10 to them. “You will be ever hearing but never understanding; you will be ever seeing but never perceiving. For this peoples’s heart has become calloused.” Our hearts may acknowledge and even recognize that still small voice of the Holy Spirit…but when it comes time to heed His direction, we quickly turn away, refusing to obey out of rebellion and selfishness. And sadly, over time it becomes easier and easier not to obey the prompting of the Holy Spirit, for over time our hearts become more and more calloused. So if today you hear His voice, trade in your heart of stone for a heart of flesh.
God’s divine viewpoint is true truth. It is the redemptive revelation, or saving truth we receive when we acknowledge Jesus Christ as our Lord and Savior. But God’s truth is also uncomfortable, and makes us squirm as we face the unlovely parts of our life. So it’s much easier to water down and bend God’s truth than to change ourselves. That’s why we’re warned in II Peter 2:20, that when those who know Christ but then become entangled and overcome by sin are worse off at the end than when they were at the beginning. For there’s only one form of the truth, and when we intentionally embrace half-truths to make ourselves feel better…it’s still sin.
We probably all know a person who has fallen away. Someone who consciously rejected the spiritual enlightenment they had once received…who had tasted of God’s goodness, but chose instead to abandon their faith. And when we intentionally reject Jesus Christ, we’re essentially saying that His sacrifice on the Cross meant nothing. For when anyone falls away, they have turned their back on God’s truth and can only then look forward to His final judgment.
