2 Kings 17:15 Israel
And they followed VANITY [EMPTINESS] and became VAIN [EMPTY] ,
and went after the nations which surrounded them,
concerning which the LORD had commanded them not to do like them.
Israel followed the unsaved people around them. Israel did the empty things unsaved people do. They went to the empty places unsaved people went. They copied the empty worship of their unsaved neighbors. Israel was so full of empty that they became empty people.
Colossians 2:8-10 The Church
See to it that no one takes you captive through philosophy and EMPTY [VAIN] deception, according to the customs of [unsaved] men, according to the elementary principles of the [godless] world, rather than according to Christ. For in Him all the FULLNESS of Deity dwells in bodily form, and in Him you have been made COMPLETE…
Believers in Christ have the fullness of God in Christ. Don't go back to emptiness and become empty! Don't trade the fullness of Jesus Christ for the emptiness of the unsaved! Follow Christ, who is the fullness of God, and you will become complete and full of the fullness of Christ.
For me to live is Christ.
