The good pleasure of goodness rightly describes what motivates us to walk worthy of the calling to which we are called. In the Interlinear Greek, good pleasure of goodness is two words eudokian “good pleasure” and agathōsynēs “of goodness.”
Good pleasure occurs 4 times. Twice of God’s good pleasure. Both times of God’s will.
3Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with every spiritual blessing in the heavenly places in Christ: 4even as he chose us in him before the foundation of the world, that we should be holy and without blemish before him in love: 5having foreordained us unto adoption as sons through Jesus Christ unto himself, according to the good pleasure of his will, 6to the praise of the glory of his grace, which he freely bestowed on us in the Beloved: 7in whom we have our redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace, 8which he made to abound toward us in all wisdom and prudence, 9making known unto us the mystery of his will, according to his good pleasure which he purposed in him… Ephesians 1 ASV
Then Paul tells the Philippians and us: “Some indeed preach Christ even of envy and strife; and some also of good will [eudokian]:”
12Now I would have you know, brethren, that the things which happened unto me have fallen out rather unto the progress of the gospel; 13so that my bonds became manifest in Christ throughout the whole praetorian guard, and to all the rest; 14and that most of the brethren in the Lord, being confident through my bonds, are more abundantly bold to speak the word of God without fear. 15Some indeed preach Christ even of envy and strife; and some also of good will: 16the one do it of love, knowing that I am set for the defence of the gospel; 17but the other proclaim Christ of faction, not sincerely, thinking to raise up affliction for me in my bonds. Philippians 1 ASV
Agathōsynēs “of goodness” only occurs twice. Both times of God’s holy ones. Once linked with good pleasure.
In Romans 15:14 “my brothers [and sisters], that you yourselves are full of goodness.In 2 Thessalonians 1:11 “To this end we also pray always for you that our God may count you worthy of the calling, and may fulfil all the good pleasure [eudokian] of goodness [agathōsynēs.”
Now, we come to the preface for Paul’s prayer for the Thessalonians and us 2 Thessalonians 1.
The only translation I can find that put’s “good pleasure of goodness” in the Bible is Young’s Literal Translation.
1 Paul, and Silvanus, and Timotheus, to the assembly of Thessalonians in God our Father, and the Lord Jesus Christ:
1:2 Grace to you, and peace, from God our Father, and the Lord Jesus Christ!
1:3 We ought to give thanks to God always for you, brethren, as it is meet, because increase greatly doth your faith, and abound doth the love of each one of you all, to one another; 1:4 so that we ourselves do glory in you in the assemblies of God, for your endurance and faith in all your persecutions and tribulations that ye bear; 1:5 a token of the righteous judgment of God, for your being counted worthy of the reign of God, for which also ye suffer, 1:6 since [it is] a righteous thing with God to give back to those troubling you — trouble, 1:7 and to you who are troubled — rest with us in the revelation of the Lord Jesus from heaven, with messengers of his power, 1:8 in flaming fire, giving vengeance to those not knowing God, and to those not obeying the good news of our Lord Jesus Christ; 1:9 who shall suffer justice — destruction age-during — from the face of the Lord, and from the glory of his strength,1:10 when He may come to be glorified in his saints, and to be wondered at in all those believing — because our testimony was believed among you — in that day; 1:11 for which also we do pray always for you,
that our God may count you worthy of the calling, and may fulfil all the good pleasure [eudokian] of goodness [agathōsynēs], and the work of the faith in power, 1:12 that the name of our Lord Jesus Christ may be glorified in you, and ye in him, according to the grace of our God and [the] Lord Jesus Christ. Young’s Literal Translation.
Kretzmann Commentary So Paul prays that God would do this very thing by fulfilling every good pleasure of goodness, that He would bring about so much in the heart of every Christian, every one without exception now taking pleasure in, being fully inclined to, all goodness. God must be not only the teacher, but also the power, supplying the strength to men who by nature are prone to evil only. He must perform the work of faith in power. Every work of every believer that springs from faith and is in accordance with faith is due to the power of the living God. Hence the believer puts all self-confidence far from him and confidently relies upon the power of God, which works in him with power.
