Pollution from the heart

I was reading my Bible the other day, I have decided to focus more on the Gospels, just to read the words and life of Jesus from the different perspectives is a pretty cool experience.
Well, I came across the following verses from Mark 7 and they really spoke to me:

The Source of Your Pollution

1-4 The Pharisees, along with some religion scholars who had come from Jerusalem, gathered around him. They noticed that some of his disciples weren't being careful with ritual washings before meals. The Pharisees—Jews in general, in fact—would never eat a meal without going through the motions of a ritual hand-washing, with an especially vigorous scrubbing if they had just come from the market (to say nothing of the scourings they'd give jugs and pots and pans).
5The Pharisees and religion scholars asked, "Why do your disciples flout the rules, showing up at meals without washing their hands?"
6-8Jesus answered, "Isaiah was right about frauds like you, hit the bull's-eye in fact:
These people make a big show of saying the right thing,
but their heart isn't in it.
They act like they are worshiping me,
but they don't mean it.
They just use me as a cover
for teaching whatever suits their fancy,
Ditching God's command
and taking up the latest fads."
9-13He went on, "Well, good for you. You get rid of God's command so you won't be inconvenienced in following the religious fashions! Moses said, 'Respect your father and mother,' and, 'Anyone denouncing father or mother should be killed.' But you weasel out of that by saying that it's perfectly acceptable to say to father or mother, 'Gift! What I owed you I've given as a gift to God,' thus relieving yourselves of obligation to father or mother. You scratch out God's Word and scrawl a whim in its place. You do a lot of things like this."
14-15Jesus called the crowd together again and said, "Listen now, all of you— take this to heart. It's not what you swallow that pollutes your life; it's what you vomit—that's the real pollution."
17When he was back home after being with the crowd, his disciples said, "We don't get it. Put it in plain language."
18-19Jesus said, "Are you being willfully stupid? Don't you see that what you swallow can't contaminate you? It doesn't enter your heart but your stomach, works its way through the intestines, and is finally flushed." (That took care of dietary quibbling; Jesus was saying that all foods are fit to eat.)
20-23He went on: "It's what comes out of a person that pollutes: obscenities, lusts, thefts, murders, adulteries, greed, depravity, deceptive dealings, carousing, mean looks, slander, arrogance, foolishness—all these are vomit from the heart. There is the source of your pollution."

There is so much packed into this chapter on so many levels, that now writing about it I don’t know where to start and stop. I think we often act very religious with how we act, we feel that is we dress the right way, say the right things, or are at the right places at the right times then we are religious and better than others. But, God cares about what is coming from our hearts, not from our vocal chords, or what others can see us do.
God cares about our hearts of worship to him, not what we look like.
I yearn to be more like Christ and to keep my heart pure in worship, not to care about doing things the way that is socially acceptable to those around me. I pray that God will keep me pure, so that I do not vomit filth, but instead have the aroma of Christ all over me!I don’t know if this made any sense to you, but it is what God has been telling me lately.
