He Will Surely Do It - 1 Thessalonians 5:23-24

1 Thessalonians 5:23-24 ESV 

Now may the God of peace himself sanctify you completely, and may your whole spirit and soul and body be kept blameless at the coming of our Lord Jesus Christ. He who calls you is faithful; he will surely do it.

He will do it if this is the desire of our heart. He is faithful if we have faith. 

Psalms 145:16

You open your hand;

you satisfy the desire of every living thing.
