Sin begins in the heart. The lust, the greed, the envy, the anger and every other evil thing starts there – deep within. The words of Jesus don’t leave much room for interpretation:
“For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies. These are the things which defile a man, …” – Matthew 15:19-20 (NKJV)
Therefore, how crucial it is that we protect our hearts from the junk that naturally forms there, collects there and then begins to rot. Consider the wisdom of Proverbs 4:23:
“Keep your heart with all diligence,
For out of it spring the issues of life.” (NKJV)
Or, as the New Living Translation puts it:
“Above all else, guard your heart, for it affects everything you do.”
Let’s be careful what we think about, what we meditate upon and in what directions our hearts might tend to go when we aren’t keeping them under control. The psalms reveal how prayer and the application of the Scriptures contain the remedies discovered by ancient men of God:
“Let the words of my mouth and the meditation of my heart
Be acceptable in Your sight,
O Lord, my strength and my Redeemer.”
– Psalms 19:14 (NKJV)
“Your word I have hidden in my heart,
That I might not sin against You.”
– Psalms 119:11 (NKJV)
Keeping our hearts in the right place takes effort, but the Lord is right there to help us in guarding them if we avail ourselves of His strength. The Holy Spirit in the heart of every believer in Jesus is more that sufficient for the task.
