1You therefore, my child, be strengthened in the grace that is in Christ Jesus. 2The things which you have heard from me among many witnesses, commit the same things to faithful men who will be able to teach others also. 3You therefore must endure hardship as a good soldier of Christ Jesus. 4No soldier on duty entangles himself in the affairs of life, that he may please him who enrolled him as a soldier. 5Also, if anyone competes in athletics, he isn’t crowned unless he has competed by the rules. 6The farmer who labors must be the first to get a share of the crops. 7Consider what I say, and may the Lord give you understanding in all things.
8Remember Jesus Christ, risen from the dead, of the offspring of David, according to my Good News, 9in which I suffer hardship to the point of chains as a criminal. But God’s word isn’t chained. 10Therefore I endure all things for the chosen ones’ sake, that they also may obtain the salvation which is in Christ Jesus with eternal glory. 11This saying is trustworthy:
“For if we died with him,
we will also live with him.
12If we endure,
we will also reign with him.
If we deny him,
he also will deny us.
13If we are faithless,
he remains faithful;
for he can’t deny himself.”
14Remind them of these things, charging them in the sight of the Lord that they don’t argue about words to no profit, to the subverting of those who hear.
15Give diligence to present yourself approved by God, a workman who doesn’t need to be ashamed, properly handling the Word of Truth. 16But shun empty chatter, for it will go further in ungodliness, 17and those words will consume like gangrene, of whom is Hymenaeus and Philetus: 18men who have erred concerning the truth, saying that the resurrection is already past, and overthrowing the faith of some. 19However, God’s firm foundation stands, having this seal: “The Lord knows those who are his,” and, “Let every one who names the name of the Lord depart from unrighteousness.”
20Now in a large house there are not only vessels of gold and of silver, but also of wood and of clay. Some are for honor and some for dishonor. 21If anyone therefore purges himself from these, he will be a vessel for honor, sanctified, and suitable for the master’s use, prepared for every good work.
22Flee from youthful lusts; but pursue righteousness, faith, love, and peace with those who call on the Lord out of a pure heart. 23But refuse foolish and ignorant questionings, knowing that they generate strife. 24The Lord’s servant must not quarrel, but be gentle toward all, able to teach, patient, 25in gentleness correcting those who oppose him. Perhaps God may give them repentance leading to a full knowledge of the truth, 26and they may recover themselves out of the devil’s snare, having been taken captive by him to do his will.
Paul introduces the doctrine of election in Eph 1:3-14, a topic in theology that is central to the apostle’s understanding of grace, redemption, and God’s sovereignty. The development of this biblical teaching in this passage is similar to what one discovers in the book of Romans 8-9. According to Ephesians 1, God’s election of believers unto salvation (and subsequent predestination to heirship) is eternal and independent of human action or will, comes from the unmerited favor (grace) of God, brings praise to God, and relates to the person of Jesus the Messiah of God.
The doctrine of election presented by Jesus and the apostles affirms that God’s choice of specific sinners was not based on any foreseen response or obedience on man’s part (such as faith, etc). Faith and obedience were the results, not the cause of God’s election. Therefore election was not determined by or conditioned on any good quality or act foreseen in man. Everyone whom God elects will be brought by the power of the Spirit to a willing acceptance of Christ. Consequently, God’s election of the sinner, not the sinner’s choice of Christ, is the ultimate cause of salvation, though God holds man responsible to believe the gospel. Scripture presents a theological tension between man’s responsibility to believe and God’s sovereign election. Though we may not be able to completely reconcile the two, Scripture presents both truths (Matt 11:27-28; Acts 13:46,48).
There are at least nine characteristics of divine unconditional election: (1) God's eternal election was made before the foundation of the world (Eph 1:4); (2) God's election was not based upon foreseen merit or good works dwelling in those whom He chose (Rom 9:11-13; 2 Tim 1:9); (3) God's election was not based on foreseen faith for faith is the result and not the ground of God's election (Acts 13:48; 2 Thess 2:13-14); (4) Election was based on the sovereign mercy of God, therefore it does not ultimately depend on man’s will but God’s will (Rom 9:16; John 1:13); (5) Election is unconditional, therefore making the salvation of the elect certain (Rom 8:29-30; John 6:37-39); (6) Election is just (Rom 9:13-24); (7) God chose particular individuals unto salvation not group election (Rev 13:8; 17:8); (8) Two fold purpose of election: (a) To result in salvation (2 Thess 2:13; 2 Tim 2:10) and (b) to result in the glory of God (Eph 1:5-6, 12-14); and (9) election is a positive doctrine of God’s work to save fallen humans and not a negative doctrine to exclude. There is no election to be separated from God, for this is the state of all humans by default, unless the individual sinner is brought to God. – SPS
