NET

12 exhorting and encouraging you and insisting that you live in a way worthy of God who calls you to his own kingdom and his glory.

Darby

12 that ye should walk worthy of God, who calls^D8787 you to his own kingdom and glory.

Darby Bible Notes

calls - Or 'the God who calls you.' but neither gives exactly the Greek, because 'of God, who calls' makes God stand by himself as such; and 'the God who calls' makes the calling too distinctive, so that, but for other reasons, one might think there was another God. The Greek preserves the absoluteness of God, and adds the calling quality.

KJV

12 That ye would walk worthy of God, who hath called you unto his kingdom and glory.
