For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.

Ephesians 2:10

And I am convinced and sure of this very thing, that He Who began a good work in you will continue until the day of Jesus Christ [right up to the time of His return], developing [that good work] and perfecting and bringing it to full completion in you.”

Philippians 1:6

God Created a Masterpiece when He created you. He has made you for a purpose and prepared good things for you to do. When you are frustrated with where you are and think you should be further along, remember to trust Him to continue shaping you and preparing you for that good work.
