1 Thessalonians 2: 13–14.
And we also thank God constantly for this, that when you received the word of God, which you heard from us, you accepted it not as the word of men but as what it really is, the word of God, which is at work in you believers. For you, brothers, became imitators of the churches of God in Christ Jesus that are in Judea.
2 Corinthians 1:20
For all the promises of God find their Yes in him. That is why it is through him that we utter our Amen to God for his glory.
