When Adam and Eve were in the garden of Eden before they sinned they did not need any rules other than the one that the Lord had given to them. They loved God and they loved each other. Their love was perfect for God and for each other because their hearts were pure. They had never known any evil.
The Lord God commanded the man, saying, “From any tree of the garden you may eat freely; but from the tree of the knowledge of good and evil you shall not eat, for in the day that you eat from it you will surely die.” Genesis 2:16,17
If Adam and Eve had never sinned then they would not have ever needed any more rules or laws to live by. The Lord only gives commandments for our good and our protection. He does not give us commandments to deprive us of anything that would be good for us. The Lord knew that it would not be good for Adam and Eve to come into the knowledge of evil. They would lose their innocence and purity. They would be tempted in ways that the Lord never designed for them to be tempted. The Lord gives the same commandment in the New Testament and that is to not have the knowledge of evil.
For the report of your obedience has reached to all; therefore I am rejoicing over you, but I want you to be wise in what is good and innocent in what is evil. Romans 16:19
The Lord wants us to wise in what is good but innocent in what is evil. We need to be mature in our thinking but babies in the knowledge of evil.
Brethren, do not be children in your thinking; yet in evil be infants, but in your thinking be mature. I Corinthians 14:20
When we become knowledgeable in evil then our thinking has become defiled by what we have seen or heard. When our thinking has become impure then we are not holy in our behavior. One sin always leads to another if we do not repent. The Lord has commanded us to be holy, which means that we are to be separate from the world and do what is right in God’s sight. Then we will be available for the Lord to use us.
As obedient children, do not be conformed to the former lusts which were yours in your ignorance, but like the Holy One who called you, be holy yourselves also in all your behavior; because it is written, “You shall be holy, for I am holy.”
I Peter 1:14-16
When we are holy then the world will know that Jesus Christ is Lord.
I will vindicate the holiness of My great name which has been profaned among the nations, which you have profaned in their midst. Then the nations will know that I am the Lord,” declares the Lord God, “when I prove Myself holy among you in their sight. Ezekiel 36:23
When we compromise and do not do what is right then we have lost the power and influence in the world that God designed for us to have with the people who have yet to come to know Him. When those who know God sin then the world may say, “they are no different than me” or “they do the same things that I do so I do not have to listen to what they say”.
Like a trampled spring and a polluted well, Is a righteous man who gives way before the wicked. Proverbs 25:26
Before Adam and Eve sinned they were holy. They lost their holiness and they lost their power. The Lord Jesus Christ came to make us holy. He wants us to be innocent in what is evil. The less we know of evil the less we will sin. The more we know of evil then the more we will sin. Evil does not destroy us unless we do it. There is a difference between evil being done to us and being around evil against our will and us voluntarily learning about evil through entertainment or deceiving ourselves by saying “there is some good in this book, movie, etc.” even though there is also the knowledge of evil. You are subjecting yourself to evil when you voluntarily learn about it through compromise. You are bringing destruction to yourself. When you bring destruction to yourself then you are also bringing destruction to anyone with whom you are in a relationship and especially a marriage relationship. The Lord loves us and gives us instructions and commandments to protect us from destroying ourselves and each other. Love keeps His commandments.
and you shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength.’ The second is this, ‘You shall love your neighbor as yourself.’ There is no other commandment greater than these.” Mark 12:30,31
When you love the Lord your God with all of your heart, soul, mind and strength and your neighbor as yourself then you will have fulfilled all of God’s commandments. You will have loved and done what is right in God’s sight. You will be holy in all your behavior. Your life will have power and evil will not destroy you.
