The most important thing I can tell you is that God is concerned about every detail of your life, including your search for the right job. The Bible says, "Nothing in all creation is hidden from God's sight" (Hebrews 4:13).
In other words, some things may seem more "spiritual" to us than others, but in reality everything we do has a spiritual side to it. If God didn't love you He wouldn't be concerned about your situation, but He does love you, and He is concerned. Remember: Jesus Christ proved that God loves us by giving His life for us. If you have never put your life into His hands, I urge you to do so today.
Don't be discouraged, and don't fall into the error of thinking you've wasted the last four years. If you hadn't gone to college, you might well spend the rest of your life in a low-paying job. Thank God for the opportunities He's given you, and trust Him to lead you to the place His has for you in the future. The Bible says, "Commit your way to the Lord; trust in him" (Psalm 37:5).
In the meantime, ask God to help you have a good attitude, and to be the best employee you can possibly be. Life doesn't always turn out the way we wish it would, but God knows what's best for us and will guide us as we pray and seek His will.
