'Fellowship' in the Bible

For the death that He died, He died to sin [ending its power and paying the sinner’s debt] once and for all; and the life that He lives, He lives to [glorify] God [in unbroken fellowship with Him].

Even so, consider yourselves to be dead to sin [and your relationship to it broken], but alive to God [in unbroken fellowship with Him] in Christ Jesus.

As for the one whose faith is weak, accept him [into your fellowship], but not for [the purpose of] quarreling over his opinions.
