Don’t mix things up. Bless others, but don’t be influenced by wrong-doers. “Do not become partners with those who do not believe, for what partnership is there between righteousness and lawlessness, or what fellowship does light have with darkness?” 2Cor 6.14 NET.
“Paul was especially fond of compounds with ‘syn’ (together). He believed in a spiritual ‘togetherness.’ … There are over 175 Greek compound words in the NT with the prefix ‘syn,’ and many of these are found only in Paul’s Epistles.” —Ralph Earle, WMNT
