God's Word about you is a written decree which predates your birth and your assignment.

[15] My frame was not hidden from You when I was being formed in secret [and] intricately and curiously wrought [as if embroidered with various colors] in the depths of the earth [a region of darkness and mystery]. [16] Your eyes saw my unformed substance, and in Your book all the days [of my life] were written before ever they took shape, when as yet there was none of them.

Psalm 139:15-16 AMPC
