Q7. What are the decrees of God?
A. The decrees of God are His eternal
purpose, according to the
counsel of His will,
whereby for His own glory, He hath fore-ordained
whatsoever comes to pass.[1]
[1] Isaiah 40:13; Romans 8:28; Matthew 10:29; Ephesians 1:34, 11; Romans 9:2223.
The decrees of God are His purposes, or what He has from eternity determined beforehand to do. The answer to this question tells us that whatsoever, i.e., everything that comes to pass has been unchangeably fore-ordained, i.e., pre-determined by God. In other words, nothing happens by chance. What ever happens, happens by the sovereign, providential outworking of Gods decrees. Moreover, His decrees are not influenced by any external factors at all. They are decreed according to His infinite wisdom and for His own glory.
Gods decrees are sometimes apprehended under two categories: general and
special. By His general decrees God determined all things and their actions and
motionnot only the good actions, but those which, from a temporal human
standpoint, may not appear good (Eph 1:11; Acts 2:23; 4:2728; Prov 16:4). Yet
God is not the author of sin (Jas 1:13, 17; 1 Jn 1:5), neither is man less
responsible for his sin, since Gods decrees do not involve an external
manipulation of the heart of sinners. Sinners sin out of their own evil
inclinations and are therefore responsible for their actions (cf. Mk 14:21).
Gods special decrees are His sovereign election and predestination of some men
and angels unto life everlasting as well as the reprobation of others unto
damnation. In this way, God makes all things work together for good to them
that love Him (who have been fore-ordained indeed to love Him), and to
demonstrate His justice against those who hate him (who have indeed been
ordained unto damnation from the beginning). Through Gods sovereign decrees,
the elect are brought eventually to believe in the Lord Jesus Christ and
preserved unto the very end. The reprobate, on the other hand, are passed by
and left to perish in their own sin, unto the praise of His own glory and His
infinite justice (Rom 9:2122).
