God's calling isn't primarily about the task assigned but about the relationship with the One who calls — faithfulness flows from knowing Him first.

1 Thessalonians 5:24

The one who calls you is faithful, and he will do it.

Romans 8:28-30

And we know that in all things God works for the good of those who love him, who[a] have been called according to his purpose. For those God foreknew he also predestined to be conformed to the image of his Son, that he might be the firstborn among many brothers and sisters. And those he predestined, he also called; those he called, he also justified; those he justified, he also glorified.

1 Corinthians 1:9

God is faithful, who has called you into fellowship with his Son, Jesus Christ our Lord.
