Biblically:

Joshua 1:3

"Every place that the sole of your foot will tread upon I have given you, just as I promised to Moses."
(Notice it’s past tense — God said it was already given, even before Joshua stepped into it.)

Deuteronomy 1:8

"See, I have set the land before you. Go in and take possession of the land that the Lord swore to your fathers…"
(The gift was already there; they just needed to claim it.)

Luke 12:32

"Fear not, little flock, for it is your Father’s good pleasure to give you the kingdom."
(It’s already granted — God delights in giving.)

2 Peter 1:3

"His divine power has given us everything we need for a godly life through our knowledge of him who called us by his own glory and goodness."
(Has given = already done, already yours.)

Jeremiah 1:5

"Before I formed you in the womb I knew you, and before you were born I consecrated you; I appointed you a prophet to the nations."
(God’s plan and calling for Jeremiah existed before he was born.)

Ephesians 1:4–5

"For He chose us in Him before the creation of the world to be holy and blameless in His sight. In love He predestined us for adoption to sonship through Jesus Christ..."
(This shows God’s purpose and blessing were decided before time began.)

Psalm 139:16

"Your eyes saw my unformed body; all the days ordained for me were written in your book before one of them came to be."
(Every blessing and assignment was already known to God before your first day on earth.)
