As we come to the end of Great Lent, we realize that it is easy to give Satan opportunity to enter into our lives and tempt us away from Christ. It can happen so naturally and mundanely that it has occurred before we realize what we have done. We turn against those around us because we have lost sight of Christ and we come to believe falsely that “my” will is the most important thing in the world, and I become willing to sacrifice everyone around me to defend and preserve my self will. In doing this we come to the fact that when we no longer are willing to let all we do be done in love for others (1 Corinthians 16:14), we have lost Christ. If we have lost Christ, we no longer have anything to say to other Christians.
Whenever we become obsessed by some past event in which we perceive that we have been wronged, we give the devil ample opportunity to lead us toward greater temptation. We forget that our warfare is not with each other! We are to engage in spiritual warfare against the Enemy of our salvation and his willing hosts, the demons. When we remember wrongs, we fall prey to the Father of Lies and engage in combat with our fellow brothers and sisters. (Joseph David Huneycutt, Defeating Sin: Overcoming Our Passions and Changing Forever, Kindle Loc. 924-27)
The antidote for Christians to this sinful self-will is Christ Himself. “I have been crucified with Christ; it is no longer I who live, but Christ who lives in me; and the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me” (Galatians 2:20). In order for Christ to become human, He emptied himself (Philippians 2:5-7). In order for us to become fully human, we need also to empty ourselves and open our hearts to Christ abiding in us. Here we realize that “the heart” of which the fathers speak isn’t the organ that pumps blood in our bodies, but refers to the spiritual reality that every person is capable of being a temple for God, or a dwelling place for Satan. The choice is ours.
Understanding these things, enter within yourself by keeping watch over your thoughts, and scrutinize closely your intellect, captive and slave to sin as it is. Then discover, still more deeply within you than this, the serpent that nestles in the inner chambers of your soul and destroys you by attacking the most sensitive aspects of your soul. For truly the heart is an immeasurable abyss. If you have destroyed that serpent, have cleansed yourself of all inner lawlessness, and have expelled sin, you may boast in God of your purity; but if not, you should humble yourself because you are still a sinner and in need, and ask Christ to come to you on account of your secret sins.
The whole Old and New Testament speaks of purity, and everyone, whether Jew or Greek, should long for purity even though not all can attain it. Purity of heart can be brought about only by Jesus; for He is authentic and absolute Truth, and without this Truth it is impossible to know the truth or to achieve salvation. (St Symeon Metaphrastis, THE PHILOKALIA, Kindle Loc. 33655-64)
This is why we prayed daily throughout Great Lent: Grant me to see my own sins and not to judge my brother.
