2 Thessalonians 2:13 AMPC

[13] But we, brethren beloved by the Lord, ought and are obligated [as those who are in debt] to give thanks always to God for you, because God chose you from the beginning as His firstfruits (first converts) for salvation through the sanctifying work of the [Holy] Spirit and [your] belief in (adherence to, trust in, and reliance on) the Truth.
