I Thessalonians 5:9

For--assigning the ground of our "hopes" (Th1 5:8). appointed us--Translate, "set" (Act 13:47), in His everlasting purpose of love (Th1 3:3; Ti2 1:9). Contrast Rom 9:22; Jde 1:4. to--that is, unto wrath. to obtain--Greek, "to the acquisition of salvation"; said, according to BENGEL, Of One saved out of a general wreck, when all things else have been lost: so of the elect saved out of the multitude of the lost (Th2 2:13-14). The fact of God's "appointment" of His grace "through Jesus Christ" (Eph 1:5), takes away the notion of our being able to "acquire" salvation of ourselves. Christ "acquired (so the Greek for 'purchased') the Church (and its salvation) with His own blood" (Act 20:28); each member is said to be appointed by God to the "acquiring of salvation." In the primary sense, God does the work; in the secondary sense, man does it.

The apostle, having spoken in the end of the foregoing chapter concerning the resurrection, and the second coming of Christ, proceeds to speak concerning the uselessness of enquiring after the particular time of Christ's coming, which would be sudden and terrible to the wicked, but comfortable to the saints (Th1 5:1-5). He then exhorts them to the duties of watchfulness, sobriety, and the exercise of faith, love, and hope, as being suitable to their state (Th1 5:6-10). In the next words he exhorts them to several duties they owed to others, or to one another (Th1 5:11-15), afterwards to several other Christian duties of great importance (Th1 5:16-22), and then concludes this epistle (Th1 5:23-28).

5:9 God’s anger (1:10; 2:16; Rom 5:9; cp. 2 Thes 1:6-10; 2:8) represents the carrying out of his judgment against evil. However, God destined believers for salvation, not wrath (2 Thes 2:13-14), and they will escape the terrors of the day of the Lord (1 Thes 5:1-3).
