9. For you recall our hard toil and struggles, brethren. We worked night and day [and plied our trade] in order not to be a burden to any of you [for our support] while we proclaimed the glad tidings (the Gospel) of God to you.
10. You are witnesses, [yes] and God [also], how unworldly and upright and blameless was our behavior toward you believers [who adhered to and trusted in and relied on our Lord Jesus Christ].
11. For you know how, as a father [dealing with] his children, we used to exhort each of you personally, stimulating and encouraging and charging you
12. To live lives worthy of God, Who calls you into His own kingdom and the glorious blessedness [into which true believers will enter after Christ's return].
13. And we also [especially] thank God continually for this, that when you received the message of God [which you heard] from us, you welcomed it not as the word of [mere] men, but as it truly is, the Word of God, which is effectually at work in you who believe [exercising its superhuman power in those who adhere to and trust in and rely on it].
