"The fears of the wicked will be fulfilled; the hopes of the godly will be granted."
Your thoughts can either build you or destroy you. The bible says, "What ever you desire, if you pray and believe you have received it, it will be yours." Mark 11:24 God wants us to have the things we desire, but they need to line up with God's word. Desires that match God's will bring us joy, peace, and courage. Ungodly thoughts bring hate, pain, and despair. Spend more time with God so that your desires come from him.
"Take delight in the lord, and he will give you your hearts desire." Psalms 37:4
