We are called to “guard our hearts” and no set of official commandments from the Lord or man-made rules from religious authorities will enable us to do that. The commands and the rules help us to have right behaviour and provide a standard to live by or, at least, live up to. But, all of that is on the outside and the heart is an inside issue. But, please note once again, that the inside “heart issues” are really the source of the outside behaviours. An understanding that seems to be have been lost in the Church and in the lives of believers today.
Jesus’ words inspired by the Holy Spirit stated … “But what comes out of the mouth proceeds from the heart, and this defiles a person. For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false witness, slander. These are what defile a person. But to eat with unwashed hands does not defile anyone” (Matthew 15:18-20).
There are four primary enemies of the heart — four life-blocking agents that become lodged in the heart, poisoning our relationships, our faith, and our character. We could spend days discussing these. But let’s just list them so that you are aware of what they are. These four damage the heart and result in the ungodly behaviours contained in Jesus astonishing comments. These four enemies of the heart are what we need to be guarding against. They are: Guilt, Anger, Greed, and Jealousy. As I said – the topic of a book in itself.
So how do we “guard” or protect the heart? Again, the topic for a whole book. But, I would suggest the root of “guarding your heart” is to first give your whole heart to the Lord. When we are truly born again we encounter Jesus as more than Saviour from our sins. He is more than our friend. He is more than our new “crisis management expert.” He is Lord. And, we need to make Him Lord. This means selling out totally to Him. Recognizing that He purchased us back from the devil by His death on the Cross of Calvary. He owns us. And we are no longer our own. As Paul writes, “it is no longer I that lives, but Christ who lives His life through me.” This selling out and truly understanding that Jesus is Lord —and personally accepting Jesus as YOUR Lord — is the starting point of being transformed, receiving a new heart, and beginning a new life “in Christ” as a ‘new creature.’
Then, He helps us to guard our new heart. His Spirit living in us helps us to deal with the issues that have wounded our heart before we met Jesus and brings healing and freedom. As He does that, we work at truly knowing how to love the Lord God with “all your heart.” The more junk and baggage that we allow the Spirit to deal with the more of our heart is free to worship, serve, and love God.
As this process continues (and it is a process or journey) we would do well to read through the New Testament (take a fresh copy and a different version so that you are free to see it with new eyes) and note the references to heart and, in particular, the need to guard it. For example, Luke 12:15 states (Jesus speaking): “Watch out! Be on your guard against all kinds of greed; life does not consist in an abundance of possessions.” As you read with fresh eyes and ears — heart eyes and ears — you will note an abundance of verses such as this one. Don’t just jot them down. Pray about them. Meditate on them. Think about them. Think about how they apply to you right now, right where you are. Deal with what the Lord reveals to you. This will free the heart up and heal the woundedness thus allowing you to truly love Him with your whole heart.
So, it is not a matter of rules and more rules. It isn’t even a matter of spiritual disciplines such as prayer, Bible reading, and fasting (which can be just more rules and more tradition). These are all things that are on the outside and they do not defile you. Often we fall back into the “religious rut” and do our praying for an hour, reading three chapters of the Bible every day, and so on. Don’t be a tradition keeper. These things are just tools to help us in our journey and often we have turned them into rules. It is what is in your heart that is the real issue right now. Not all the external structure and routines that we fall back onto most times. Don’t become one of The Tradition Keepers.
As you move forward in this you will note that you are experiencing more and more freedom and feeling more spiritually alive and alert than ever before. That is great. So great. But, don’t let your guard down as there is so much more to experience. So, “guard your heart” and aim for the goal of loving the Lord your God with ALL your (healed and set free) heart.
