You would only be telling them part of the story. You should read Romans 8:16 and Galatians 4:4-7 and tell them that when we believe, we are adopted as children, and then that adoption, the manifestation, unveiling, revealing of who the children of God are, and the receiving of the inheritance takes place at the resurrection or transformin of the body at the coming of Christ.
I'd say that
Predestination is of existing saints to adoption/glorification, not sinners to conversion. (Eph. 1:5, 11; Rom. 8:23, 29-30)
Election is to service, calling and purpose, not to salvation. (Isa. 42:1; Acts 9:15; Rom. 11:28)
Adoption is the future redemption of the body, not conversion. (Rom. 8:23, 15-17; Gal. 4:1-6)
Sinners become sons of God through the new birth, not through adoption. (John 1:12-13)
There are 2 callings: Gospel and vocational, not inward or outward or effectual or ineffectual, etc… (2 Thess. 2:14; Eph. 4:1; Rom. 8:28; 2 Cor. 5:20)
Christ’s life, not his death is what saves. (Rom. 5:10; 1 Cor. 15:17)
Sinner is saved by regeneration, not atonement. (Tit. 3:5)
Glorification is what’s limited, not atonement. (Rom. 3:23; 8:17-30)
