There you go !
Two entities in One !
Both capable of operating independently from the other.
Scripture ascribes God’s various works in the economy of redemption to a particular member of the Trinity. The Father is particularly singled out as the Creator (1 Pet. 4:19); the p 192 Son is distinguished as the Redeemer and Mediator (Rom. 3:24; Eph. 1:7; 1 Tim. 2:5); and the Spirit is identified as the agent of sanctification (2 Thess. 2:13; 1 Pet. 1:2).44 The external works of the Trinity in the economy of redemption therefore reflect the order established by the internal works of eternal generation and procession within the divine life. The Father sends the Son in the economy of redemption because he begets the Son eternally. The Spirit is sent by the Father and Son ad extra because he eternally proceeds from them ad intra.
Nevertheless, in all these works, all three persons of the Trinity work inseparably together (cf. John 14:10). Though one person or another may be emphasized in a particular work, no one person does any work exclusive of the other two persons, for, as the classic dictum states, “the external works of the Trinity are undivided” (opera Trinitatis ad extra indivisa sunt). Note, for example, the following passages, which ascribe the works outlined above to the other persons of the Trinity:
1. Creation and preservation
a. Through the Son (John 1:3, 10; Col. 1:16–17; 1 Cor. 8:6; Heb. 1:2–3, 10)
b. Through the Spirit (Gen. 1:2; Job 26:13; 32:8; 33:4; 34:14–15; Ps. 104:30)
2. Redemption
a. Through the Father (1 Chron. 17:21; Isa. 63:16; Gal. 4:4–5)
b. Through the Spirit (Heb. 9:14; Rom. 8:11)
3. Sanctification
a. Through the Father (John 17:17; 1 Thess. 5:23)
b. Through the Son (1 Cor. 1:30; Eph. 5:25–27)
44 Another way of stating this is that the plan of redemption is attributed to the Father, the accomplishment of redemption is attributed to the Son, and the application of redemption is attributed to the Spirit. Still another alternative is to say that in the economy of redemption, all things are from the Father, through the Son, and in the Spirit.
