Since, then, you have been raised with Christ, set your hearts on things above, where Christ is seated at the right hand of God. Set your minds on things above, not on earthly things."
This doesn't mean that we just ignore our situations and pretend like they don't exist. Not at all! But our circumstances should not determine our happiness and joy. We can take all our burdens to God and leave them there; let Him carry them. Keep your eyes fixed on God. He loves you so much that He sent His only Son to die for you. Jesus is now seated at the right hand of the Father interceding for you. He sent His Spirit to be our Comforter and Guide. His grace is sufficient and His mercies are new every morning; great is His faithfulness! We can boldly enter into the throne room of the Creator of the universe. This should give you joy!
I have told you this so that my joy may be in you and that your joy may be complete. John 15:11
In these last days we need to be even more aware that we have an enemy who wants to see us defeated. John 10:10 says that the thief comes to steal (our joy), kill and destroy. But Jesus has come so that we may have life!
So go to the enemy's camp and take back what's he stolen from you. He's under your feet. Greater is He that is in you than he that is in the world. Ask God to restore the joy of your salvation and create a new heart in you. Then shout for joy to the Lord!
I've got the joy, joy, joy, joy down in my heart to stay!
