REMEMBER - being a Christian does not get you a free pass to heaven NOR does knowing the Scriptures - Be sober, be watchful. Your adversary, the devil, prowls around like a roaring lion seeking someone to devour (1 Pet 5.8)
Destroying CHRISTIANITY from within - antichrists

Falsehood - and only falsehood - separates us from God ... False thoughts, false words, false feelings, false desires - Behold the aggregate of lies that leads us to non-being, illusion, and rejection of God.
(St. Nicholas of Serbia, Thoughts on Good and Evil)

Only one who guards himself from all sin can have sincere and fervent faith. Faith is only preserved in the presence of good morals.
(St. Nikon of Optina)

Our world is guided by two principles and sources: God and the devil. All that is better in the world of men has its source in God, and all that is bad has the devil as its principle and source.

In the final account, all good comes from God, and all evil from the devil.
(St. Justin Popovich, Explanation of I John 3:11)

God and the devil are found at opposite poles. No one can turn his face to God who has not first turned his back on sin. When a man turns his face to God, all of his paths lead to God. When a man turns his face away from God, all of his paths lead to perdition.

When a man finally rejects God by word and in his heart, he is no longer fit to do anything that does not serve for his complete destruction, both of his soul and of his body.
(St. Nicholas of Serbia, Thoughts on Good and Evil)

Adorn yourself with truth, try to speak truth in all things; and do not support a lie, no matter who asks you. If you speak the truth and someone gets mad at you, don't be upset, but take comfort in the words of the Lord:

take comfort in the words of the Lord: Blessed are those who are persecuted for the sake of truth, for theirs is the Kingdom of Heaven (Matt. 5:10).
(St. Gennadius of Constantinople, The Golden Chain, 26,29).
