So far in 2 Timothy, Paul has reminded Timothy to follow his example and get on with his calling – fanning into flame his gift. He’s been given God’s power to carry out the mission, so he shouldn’t be ashamed of anything – whether it be the gospel itself, or Paul’s imprisonment for the sake of it.
Today, Paul reminds Timothy that just as he’s been equipped by God to do the work, he’s also been given a great motivation for the work: God’s grace.
