Daily actions have a lot to do with what we carry internally because we really act according to the things that our hearts treasure.
Perhaps you can easily see what we carry externally, but what we carry in our hearts you cannot see, just look at actions that direct you to interpret the fruits that a person has treasured in his life by the way you act.
And in this way the Lord Jesus who knows our hearts and what we carry in him tells the Pharisees in the book of Matthew in his chapter 5 verse 7 what they truly were.
Matthew 15: 7-11
7 Hypocrites, Isaiah well prophesied of you, when he said:
8 This people of lips honor me;
But, his heart is away from me.
9 For in vain they honor me,
Teaching as doctrines, commandments of men.
10 And calling the crowd to himself, he said to them, Hear, and understand:
11 Not what enters the mouth contaminates man; but what comes out of the mouth, this contaminates the man.
In these verses we can understand that Jesus knew perfectly what was in his heart and what they machined in his thoughts and although they spoke beautifully they adorned the words and demanded things of the law that appealed to see that they practiced them but were not really willing to fulfill
Then Jesus confronts them and calls them hypocritical hypocrites and makes them see that they honored his lips so that the world could see them but their hearts were far from Him since they had not been born again because they practiced doctrines imposed by men however they did not have absolutely nothing that He had come to bring humanity.
The Pharisees talked about what they had in their hearts and could not hide it because their hearts were contaminated and the Lord also makes them see that what goes into the mouth does not contaminate man but what comes out of the mouth because really what we say is what we carry inside.
¡What comes out of our mouth is our identification of who we are! In our hearts we keep everything inside us and it is from there that our actions derive.
