When we spend time with God on a daily basis, focusing on His Word, a cleaning and refreshing is actually taking place. God is not only renewing our mind (making it fresh), He's purifying our hearts and renewing our spirits. Psalm 51:10 - Create in me a clean heart oh God, and renew a right spirit within me. When we don't spend time with God, we will begin to notice our spirits become cluttered. We'll not react to situations in a Godly way, our peace will be robbed, our joy will be robbed, our spiritual vision will become blurry, and our hearts will become hard. When we are in the Word everyday, God has a chance to bring out the impurities that we carry in us and wash them away. Our spirits will be refreshed.
Before I head out into the craziness of life today...I'm taking a moment with Him so that He can clean my heart and refresh my spirit. If life is getting you down and making you crazy...let Him clean the house of your heart and refresh you today.
