that Christ may dwell in your hearts through faith; to the end that ye, being rooted and grounded in love,

τεθεμελιωμένοι, tethemeliōmenoi “founded,”

if so be that ye continue in the faith, grounded and stedfast, and not moved away from the hope of the gospel which ye heard, which was preached in all creation under heaven; whereof I Paul was made a minister.

And the God of all grace, who called you unto his eternal glory in Christ, after that ye have suffered a little while, shall himself perfect, establish, strengthen you.
