This term is usualy used in the new testament in the following way - not a compliment.

1. A very religious person who loved to teach and preach but did not obey his own teaching - A Hypocrite

2. A very strict person at times loving to burden people with unnecessary rules and regulations. Unforgiving when for example the women was caught in adultery, yet Christ forgave her. Loving the so called letter of the law not the spirit.

3. A liar. Christ said they were of there father the devil, the father of liars. They sinned with there lips in this way.

Christ said let your ye be ye and your no be no. Even sincere Christians can make the mistake of saying things they don't do. We must not say yes to something, or no, unless we are one hundred percent sure we mean it and are willing to carry it through. Let your yes be yes and your no, no.

Matt chp 5.

4. Did not have a personal daily relationship with God through Christ. True Christians are bond servants to Christ, He redeemed us and bought us. We are not at all free in that sense. We are bound to do His will and walk with Him in all things, decisions etc.

Go away says Christ to the Pharisees at His return. They had preached, taught and thought they had lived the life, I never knew you, says Christ, they never had a moment by moment relationship with there Lord and Master.
