New American Standard Bible (NASB)
1 Thessalonians 3
9 For what thanks can we render to God for you in return for all the joy with which we rejoice before our God on your account,
10 as we night and day keep praying most earnestly that we may see your face, and may complete what is lacking in your faith?
11 Now may our God and Father Himself and Jesus our Lord direct our way to you;
12 and may the Lord cause you to increase and abound in love for one another, and for all people, just as we also do for you;
13 so that He may establish your hearts without blame in holiness before our God and Father at the coming of our Lord Jesus with all His saints.
1 Thessalonians 4
1 Finally then, brethren, we request and exhort you in the Lord Jesus, that as you received from us instruction as to how you ought to walk and please God (just as you actually do walk), that you excel still more.
2 For you know what commandments we gave you by the authority of the Lord Jesus.
3 For this is the will of God, your sanctification; that is, that you abstain from sexual immorality;
4 that each of you know how to possess his own vessel in sanctification and honor,
5 not in lustful passion, like the Gentiles who do not know God;
6 and that no man transgress and defraud his brother in the matter because the Lord is the avenger in all these things, just as we also told you before and solemnly warned you.
