Titus 1:15 says that for those who are pure, everything will be pure. And for those who are corrupted, both their minds and conscience are corrupted.
So it is really important to be pure, otherwise our lives will be corrupted totally and the consequences are worse. Let us see who is pure and who is corrupted.
He is pure whose sin is washed away
In Isaiah 1:25, Lord says that He will turn His hands towards us to purge away our dross and remove all our impurities. If we are washed by the Lord Himself, then we will be pure.
To perform sin through one’s deeds will make one corrupted. Read Psalms 106:38,39. To perform idol worship is a sin that will make one corrupted Ezekiel 36:25, I Thess. 1:9.
He is pure who is free from rebellion
Job 33:9. Lord says in Jeremiah 5:6 that rebellion will bring about backsliding. As said in Psalms 51:3, those who rebel against the words of the Lord and perform sin will know what is wrong and purposefully do it. Therefore one cannot escape from God’s wrath by rebelling.
He is pure who listens to and follows God’s words
John 15:3. Ephesians 5:26,27 and 1 Peter 1:22 clearly say that one can be cleansed only by the word of the Lord. Those who follow God’s commandments in accordance with their spirit will always be pure.
He is pure who does not join others’ sins
The best example for this is Judas, who deceived Jesus Christ. He went and sat together with chief priests and the officers of the temple guard (who were all against Jesus) and decided to get money from them to deceive His beloved Jesus. Another good example is Sapphira, who went along with her husband’s sin (Acts 5:9. Read II Thess. 3:6, II John 1:10,11).
