2 Timothy 1:8
8Therefore don’t be ashamed of the testimony of our Lord, nor of me his prisoner; but endure hardship for the Good News according to the power of God,
Therefore—because God gave power, love, and self-control—do not be ashamed of the testimony of our Lord, nor of Paul His prisoner. Share in suffering for the Good News according to the power of God.
The power is given to be used in costly witness. Shame is a live temptation; grace that can be resisted must be drawn on so Timothy actually stands with the gospel and the chained apostle.
The “therefore” leans on the Spirit of power already given. The God who endues with power is the same God by whose power Timothy is to suffer.
Comfort: suffering for the gospel is not self-wrought heroism. God supplies the power that keeps a minister unashamed of Christ and of Christ’s imprisoned servant.
