Philippians 4:5 says, "Let your moderation be known unto all men. The Lord is at hand."
Moderation in the Scripture means self-control or self-discipline. Many problems in our society such as adultery, fornication, drug abuse, alcoholism, nicotine addiction, etc., are caused by a lack of self-control in the lives of individuals. Galatians 5:23 says one of the fruits of the Holy Spirit in our lives is temperance or self-discipline. If we have rule over our own spirits and lives, we will have the fruit of self-control in our lives.
I won't dispute the word of God which you have posted, yet I wonder if the issues you addressed such as adultery, fornication, drug abuse, addiction is a matter of self control alone? Do you feel you could add to this in how one would apply that to their lives while facing such struggles. I ask because I have some addictions and it's been very difficult for me.
Blessings.
