You have a part of your being called a determiner, or will. You can determine, or will to believe in Jesus, obey Him, and change yourself and your ways to line up with His. You can determine to pray, study, fast, etc. You can determine to have a strong relationship with the LORD God, or you can determine to go after the world and the temptations in it. You can determine to drink alcohol, do drugs, and live in sin, or not. Use this power in you very wisely. It is the ability to spend eternity in Heaven or Hell, for you choose one of these by an act of your will. Choose wisely, and then determine in your heart to follow HIM!
