10 Create in me a clean heart, O God,And renew a steadfast spirit within me. — Psalm 51:10 NKJV
What is a clean heart, how do we get it and why is it important to be sure that we have clean hearts? An unclean heart is a heart that contains bitterness, hatred, deciet, lust, envy, coveteousness and the list goes on and on to including anything that would cause us to sin. The opposite of that would be a heart that contains only love. It is impossible for us to clean our hearts. We need the Holy Spirit, who is love, to do that for us. We can make all the resolutions and follow all the self-help programs we can find, but in the end, without the Holy Spirit, we will still have unclean hearts. Those programs may remove the filth from the heart but they will leave it empty. An empty heart is what the evil spirits are searching for.
24 “When an evil spirit leaves a person, it goes into the desert, searching for rest. But when it finds none, it says, ‘I will return to the person I came from.’ 25 So it returns and finds that its former home is all swept and in order. 26 Then the spirit finds seven other spirits more evil than itself, and they all enter the person and live there. And so that person is worse off than before.”– Luke 11:24-26 NLT
Our hearts must be filled with love and that only comes from the Holy Spirit. Once we accept Jesus and His Spirit abides within us, He will keep our hearts clean, if we allow Him to do so. Clean hearts are necessary because it is “out of the abundance of the heart that the mouth speaks”. It is also where our thoughts come from, so we must be sure that the source is clean or our thoughts, words and actions will be displeasing to God.
