The plan of this study is simple. We will look at a large number of sins, one by one, alphabetically. We will define the sin, describe it, and comment on it, along with noticing Scripture references on the particular entry. Some illustrations will be offered along with the description.
You have thoughts and I have thoughts. This is part of what makes us human beings. Thoughts are neither right nor wrong in themselves. But do you ever have evil, wrong, and sinful thoughts? Be honest with yourselfand with God. All of us have had to admit our falling into thoughts that were not the highest, the noblest, the purest, and the most loving.
The Lord Jesus declared, From within, out of the heart of men, proceed the evil thoughts and these defile the man (Mark 7:21-23). The thought life may bring good and also bring bad, so it is important that we carefully guard our heart and mind. Watch over your heart with all diligence, for from it flow the springs of life (Proverbs 4:23). As he thinks within himself, so he is (23:7).
Jesus said, The good man brings out of his good treasure what is good; and the evil man brings out of his evil treasure what is evil (Matthew 12:35). Thus, our words reveal what is in our heart: The mouth speaks out of what which fills the heart (v. 34).
Our thoughts come from our mind or heart, and God tells us, The heart is more deceptive than all else and is desperately sick; who can understand it? (Jeremiah 17:9). The thoughts of the unbeliever are just as deceitful as his heart.
This is why God says, My thoughts are not your thoughts, nor are your ways My ways, declares the Lord. For as the heavens are higher than the earth, so are My ways higher than your ways and My thoughts than your thoughts (Isaiah 55:8-9). Since our thoughts are not Gods thoughts, we can understand that those thoughts are sinful and evil.
Think of the sins that originate in the thought life. Envy is an inward sin but it arises from our thoughts (Galatians 5:19-21). Jealousy also comes from the heart (2 Corinthians 12:20). Hatred comes from the heart (Titus 3:3), as does lust (Matthew 5:27-28). Impurity (Galatians 5:19), anger (Ephesians 5:31), and malice (Romans 1:29) are all sins that have their source the human heart.
The thought life does matter! Evil thoughts are responsible for many external sins, for a corrupt heart and mind produce corrupt thoughts that manifest themselves in overt deeds. This is why Paul says that you are to be transformed by the renewing of your mind, so that you may prove what the will of God is, that which is good and acceptable and perfect (Romans 12:2).
Lets be sure of this: We will not only be held accountable for our actions, our deeds, or our works (Revelation 22:12), as well as our words (Matthew 12:34-37), but we will need to face God in judgment and give account for our thoughts. God will judge the secrets of men through Christ Jesus (Romans 2:16).
On the Last Day, Christ Jesus will both bring to light the things hidden in the darkness and disclose the motives of mens hearts; and then each mans praise will come to him from God (1 Corinthians 4:5; Ecclesiastes 12:14). Are you prepared for God to examine your thoughts to this extent?
