Psalm 119:7 says:
I will praise thee with uprightness of heart, when I shall have learned thy righteous judgments.
That verse says that it is His word, His law, His precepts, His judgments, His commandments, His ordinances, His testimonies, His statutes, His way is what shows us what's right. A lot of people have got it backward, wanting some type of change to happen inside and then they will do what's right but once you've accepted Jesus, you've been changed. What needs to happen is we need to do what is says in Romans 12:2 (And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.).
A lesson for the day: It is far better to seek the truth than to seek happiness.
