1 Thessalonians 4:6,7 - The Lord has called us for holiness

4:6

"That no one transgresses and wrongs his brother". We often think of sexual immorality in terms of "me", "why shouldn't I be allowed to do this?" If we commit sexual immorality we both transgress God's law and we hurt other people. Then there is a solemn warning, God will avenge all wrongs. When there are natural disasters such as floods someone will often pipe up that it has happenedas a judgement from God, and such a person will be widely mocked, sometimes rightly so. However, God is an avenging God, and sin invites retribution. Both the Old and New Testaments are consistent and clear on this, including Jesus Himself. 

4:7

"For God has not called us for impurity, but in holiness". We need to be aware of what we have been called for. And notice how everything is God centred. All too often our thinking and teaching starts with man and adds God in later, this is a deeply unbiblical approach, which will never lead us to the truth.
