Purity begins in your thoughts...If you occupy yourself with unholy thoughts, you are not giving God the place that is due Him. Remember the scripture that tells us to "Love the Lord your God with all your heart, with all your soul, and all your strength"? When you love the Lord with ALL your heart, with ALL your soul, and with ALL your strength...how can impure thoughts ever be a part of your day? Our desire should be to have a pure heart like what is described in Psalms and be steadfast in our pursuit of right living. A heart full of sin has no room for purity.
I look at this field of lavender and I see peace, purity and tranquility. That is what God wants for us...keep our hearts and minds pure so that we can enjoy a life of peace and tranquility. This doesn't put us above others, only means we are striving daily to keep our hearts pure so that we can be a light in our corner of the world.
