Purify your heart from all dirtiness and keep it clean, so that God may come and dwell in your bosom and you be filled by the Holy Spirit and His godly gifts. My beloved children, this should be your only purpose and care. This should always be your purpose and quest. Pray for this to God.

Seek God every day in your heart, not outside of it. When you will find him, be with fear and tremble because your heart has become God’s throne. But in order to find God, be humble, because He despises the proud ones and loves the ones humble in their heart.

(Translation from Saint Nectarios of Pentapolis, Învăţături, traducere din limba greacă de Ieroschimonah Ştefan Nuţescu, Editura Evanghelismos, Bucureşti, 2009, p. 15)
