God has always had the same eternal purpose for each person.  Whether it was Noah or Abraham–many years before the Old Testament law, David under the law, or Christ, the apostles or his children under the new the law, he aimed to have his eternal love in each mind and heart.  He said: Let this mind be in you, which was also in Christ Jesus (Phil. 2:5), Forasmuch then as Christ hath suffered for us in the flesh, arm yourselves likewise with the same mind (1 Pet. 4:1).

His plan is for every child to be thoroughly prepared for every good work is based in the perfection (completion) of a good heart (2 Tim. 3:17).  His plan to furnish his children unto every good work is accomplished by first purging the evil out of the inner man (2 Tim. 2:20, 21).  His plan to prepare the church as a bride for her husband (Rev. 21:2) is accomplished by taking out every spot, wrinkle and blemish (Eph. 5:26, 27).
