So, do not be ashamed to testify for our Lord, or ashamed of [being associated with] me, His prisoner, but [be willing to] suffer hardship with me for the sake of the Gospel, relying on God's power [to sustain you].

for which I am suffering difficulty [here] in prison, as [though I were] a criminal. But God's message is not "in prison."

So, I endure everything for the elect's sake [i.e., God's people], so that they can obtain the salvation which comes through Christ Jesus, with [its] never ending splendor.

However, the solid foundation of God stands firm. [Note: This probably refers to the church. See I Tim. 3:15]. It is sealed with these words [i.e., certifying God's ownership and a commitment to Him]: "The Lord knows those who are His people," [See Num. 16:5], and "Everyone who confesses the name of the Lord should stop practicing wickedness." [See Isa. 36:13].

If a person rids himself of the common ones [i.e., the influences of evil people and qualities], he will be an instrument for [God's] honor, dedicated, suitable for use by the Master, [and] prepared for [doing] every good deed.

May the Lord be with your spirit [i.e., close to you]. May God's unearned favor be with you.
