Throughout Paul’s letters to Timothy, he employs military language in order to convey the seriousness of Timothy’s call to the pastorate at Ephesus. Paul understood the significance of their mission in the fight for the truth. Now, he is passing that fight onto his young disciple. Paul has been at frontlines of ministry — these, then, are his dispatches from the front in order for Timothy to take over the campaign.
“Indeed, we have all received grace upon grace from his fullness.” (John 1:16)
