Hebrews 5:9 (NASB)

And having been made perfect, He became to all those who obey Him the source of eternal salvation,

Job 36:4 (NASB)

For truly my words are not false; one who is perfect in knowledge is with you.

Deuteronomy 32:4 (NASB)

The Rock! His work is perfect, for all His ways are just; A God of faithfulness and without injustice, Righteous and upright

is He.

God is perfect we can all try but without Christ we will always fall short.
