God gave us His commandments to define what is lawful. God’s law is Holy. His commandments are Holy, righteous, and good. God defines what is sinful. Moreover, God gave each of us a conscience, an inner sense of right and wrong. One reason is because He loves us, and He doesn’t want us to destroy our lives and the lives of others through our evil deeds. But He also gave it to us to show us our need for Christ. He alone can forgive our sins, change our hearts, and then help us live the way we should.
The conscience is defined as that part of the human psyche that induces mental anguish and feelings of guilt when we violate it and feelings of pleasure and well-being when our actions, thoughts, and words are in conformity with our value systems. The Greek word translated “conscience” in all New Testament references is suneidēsis, meaning “moral awareness” or “moral consciousness.” The conscience reacts when one’s actions, thoughts, and words conform to or are contrary to God’s standard of right and wrong.
When King Solomon rebuked someone who had wronged his father, he said, “You know in your heart all the wrong you did” 1 Kings 2:44
Tragically, our conscience—this inner moral compass that ought to point us to right and wrong—can become dulled and suppressed, and we may not even be able to hear its warnings. Instead, we deliberately choose to do wrong—and the more we do this, the more calloused or hardened our conscience becomes. Some people, the Bible says, “suppress the truth by their wickedness” Romans 1:18

The world is increasingly suppressing God’s truth and is now openly opposed to it. It has embraced evolution and naturalism so that Man can make up His own rules. Christians who hold to God’s values are being treated as bigots and haters. Jesus said that in the last days before He returns this would be the case and we need to prepare for it.
“”Then they will deliver you up to tribulation and put you to death, and you will be hated by all nations for my name’s sake. And then many will fall away and betray one another and hate one another. And many false prophets will arise and lead many astray. And because lawlessness will be increased, the love of many will grow cold.” Matthew 24:9-12
As Christians, we are to keep our consciences clear by obeying God and keeping our relationship with Him in good standing. We do this by the application of His Word and submitting to the indwelling Holy Spirit’s leading. We need to help those whose consciences are weak, treating them with Christian love and compassion. Don’t give in to cynicism or despair but ask God to help you point others to Christ’s transforming power.
