The heart is the most important part of the human body for in it flow blood and life of both physical and invisible realm. The Bible instructs us to guard our hearts above all else because it can determine the where you are headed in life (see Proverbs 4:23).
From what things should we guard the heart with? We need to guard our hearts from the defilements caused by this evil world through hurts, offenses, temptations and such things. Jesus said in Matthew 15:11, “Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.”
The words that come out of our mouth are the very issues buried deep inside – the wounds, the scars and the bitterness one has allowed in his or her life. We must protect our heart from such things. If our heart is full of darkness, anger, hurt, pain and unforgiveness then we are headed towards the path of destruction. But this can be avoided by guarding our hearts.
And the only One who is capable of guarding and protecting our heart is God, the Maker of our hearts. “He fashioneth their hearts alike; he considereth all their works.” (Psalm 33:15).
First, you come to God and surrender your heart to Him. Tell God that you give Him the permission and authority to take over your heart. For we know, God never violates our free will and you have to tell God you are willing to let Him handle your heart.
Second, your heart can be guarded through meditating the Word of God. You know how life can sometimes make you anxious, angry, and wounded. All these offenses can’t be avoided because we live in a world that is cursed and corrupted. But Jesus Christ left gave us the Holy Spirit to be our Guide, Fellowship and Helper both in Spirit and in Truth. The Holy Spirit will help us overcome these things by meditating on the Words of God:
“And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.” (Philippians 4:7)
“These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.” (John 16:33)
Lastly, it is the peace of God inside you that will be able to guard your heart and mind as mentioned in Philippians 4:7. Jesus Christ is the Prince of Peace and the very first who has overcome the world. We know how Jesus Christ had lived on the earth and he encountered different kinds of people who were difficult to love; people who betrayed him, rejected him, lied about him, yet he overcome because the peace of God was with him. And that is why Jesus told us many things before he left this world so that we may also overcome the world as he did.
Therefore, you continually set your eyes upon Jesus, rest upon His words and yield to the Holy Spirit so that your heart will be guarded from the evil surrounding you.
