He is a rewarder of those who diligently seek Him.
Hebrews 11:6 (NKJV)
Keep your heart with all diligence, for out of it spring the issues of life.
Proverbs 4:23 (NKJV)
We shall reap if we do not lose heart.
Galatians 6:9 (NKJV)
Diligence qualifies our work for God. It's 'how' we are to do our work. We are to 'Diligently heed the voice of the Lord' (Exodus 15:26), 'Diligently keep the commandments of the Lord' (Deuteronomy 6:17), teach our children with diligence (see Deuteronomy 6:7), and lead with diligence (see Romans 12:8).
When King David was overwhelmed with trouble, 'I am so troubled I cannot speak' (Psalm 77:4), he made a 'Diligent search' (v.6) of God's past goodness to find comfort and direction.
So what exactly is diligence? It is a 'constant and earnest effort' (Random House Dictionary). It is a 'steady and careful application' (World House Dictionary). Note the words 'constant' and 'steady.' In other words, don't give up.
Don't stop trying. Don't stop auditioning. Don't stop hoping, believing, and moving forward in your work. If Satan cannot have your immortal soul because you believe upon Jesus, then he will try to steal your work. How?
The enemy will whisper, 'You can't do this.' He'll scream, 'Stop.' He'll enlist the help of dream haters. He'll throw obstacles in your path. He'll try to steal the fruit from your tree and the fans from your shows... by tempting you to give up.
So don't stop. Be diligent (constant and steady). The result?
'The plans of the diligent lead surely to plenty' (Proverbs 21:5); 'The soul of the diligent shall be made rich' (Proverbs 13:4). Basically, success.
Consider God's path to success a rocky road, an obstacle course, or a series of tough auditions. You may not see the finish line, but you know Who wins. He gives away the ending, and He gives away His life to help us.
Therefore, be diligent to help others. Be diligent in your work. Be diligent to become a star for God.
