Since God was the One who came into this earth first, we must seek Him first, too. It is because He knows everything, He is the best and He is our loving Creator. He also wants us to come to Him and be His friends and acknowledge Him as our Heavenly Father. Matthew 6:33 that we must seek His Kingdom first and His righteousness, and all these things shall be added unto us.
If we just earnestly seek Him with all of our hearts and put Him first in everything, blessings and grace will follow. It is His promise. Once we trust in His Name and lean not on our own understanding, and once we acknowledge Him in every ways, He will direct our paths (Prov. 3:5-6). He will guide us to the best things in life. Not our will, but His will be done.
In any decisions and plans that you will make, seek God first. Serve Him with all of our hearts without grumbling. Then, everything will just follow. Seek the Kingdom of God above all else, and live righteously, and He will give you everything you need.
