Unto the pure all things [are] pure: but unto them that are defiled and unbelieving [is] nothing pure; but even their mind and conscience is defiled. (Titus 1:15 [KJV])
The modern concept of transparency in governance policies and management and in customer cares services etc. is good for those that are pure, for the defiled it is a bad concept. For those who have everything to hide, an open office is a bad idea; they would like to operate on privacy mode all the time. Do all things behind closed doors, behind sound proof walls, behind secured enclosures, away from the CCTV. They would rather leave in privacy because they are not comfortable amidst others, where they live a false life of pretence. The heart is not deceptive, that is where the true you resides. Inside there, is where you reside and what you do especially in privacy is what you really are.
Psalmist says; “I delight to do thy will, O my God: yea, thy law is within my heart.” Psalms 40:8. The pure in heart, have preserved their spirit and their minds, so their character is pure; the defiled and unbelieving, have corrupted their minds and their spirit and so, their character testify to that. It is hard to do right when you heart is full of evil or is accustomed to evil doing. For example one who is talking ill of others will always want to do that whenever he meets other people; he has no good things to talk about, is such talks of interest he can maintain conversation while those not in habit of doing so would feel uncomfortable to in the presence of such people. The moment you entertain such a person once with a little bit of interest, they believe to have found a friend their kind of friendship is based on ‘they talk and you listen with interest.’
Those who have determined to be pure in heart, will put in what is pure, to guard what comes out. “The mind must be fed with pure food if the heart be pure. . . It is impossible for the youth to possess a healthy tone of mind, and correct religious principles, unless they enjoy the perusal of the Word of God. – Sons and Daughters of God, p.108. What you stock is what you will eat; you cannot get what you did not store. The heart is a storehouse. It can store good and bad; therefore, it requires prudent management.
