The Bible's message is simple but profound. True happiness is possible but seems elusive because people seek it in the wrong way. Happiness pursued apart from the way that God has directed is man-centered and futile. Happiness is found in the law of God, in avoiding the path of sin; it is the indirect result of holiness.
The Law of Liberty
By His Word, God has brought us forth for the purpose of bearing fruit. There's nothing worse than bringing shame to the name of Christ by our moral hypocrisy.
Christ and the Law
The Scripture says that both the legalist and antinomian are coming to God in their own self-righteousness. They are not coming in the righteousness of Christ.
