6 Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience. 7 Therefore do not become partners with them; 8 for at one time you were darkness, but now you are light in the Lord. Walk as children of light 9 (for the fruit of light is found in all that is good and right and true), 10 and try to discern what is pleasing to the Lord.
Just because we can repent and be forgiven doesn’t mean that we shouldn’t try to please God in everything we do. Walking in darkness with others is dangerous to the health of our relationship with God. The fruit of light is comparable to the fruit of the Holy Spirit as described below:
22 … the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23 gentleness, self-control; against such things there is no law.
