Yes, you can ask God to increase you, to bless you and to prosper you. He wants you to delight in abundant prosperity. Jesus came for our salvation and so we may live an abundant life and with Jesus God has freely given us all things. This prayer helps you ask for increase and blessings. 

The heavens are the heavens of the LORD, But the earth He has given to me. He has Brought me to the land which he swore to give to my ancestors Abraham, Isaac, and Jacob, and It now belongs to me. It is filled with great and splendid cities which I did not build, and houses full of all good things which I did not fill, and hewn cisterns which I did not dig, vineyards and olive trees which i did not plant, and every day I eat and am satisfied. I am humble always remembering my father and I have inherited the land And will delight in abundant prosperity. I will not be not haughty, nor trust in uncertain riches, but in the living God, who gives us richly all things to enjoy. My God will meet all my needs according to the riches of his glory in Christ Jesus, because God who did not spare his own Son, but gave him up for me and with him freely gave me all things. Everything God has is mine. I will let no debt remain outstanding except the continuing debt to love one another. The LORD has opened the heavens, the storehouse of His bounty, He sends rain on my land in season and He blesses all the work of my hands. I will lend to many nations but will borrow from none. I am generous and I am blessed, for I share my food with the poor. I give with a cheerful heart. 

In Jesus name - Amen
