"Filled with the HolySpirit, Jesus returned from the Jordan and was led by the Spirit into the desert" (St. Luke 4:1).
You see, brethren, what it means to be filled with the Holy Spirit of God. Without the Spirit of God, man is filled with worries: where he will go and how he will go. But with the Spirit of God man is without those worries. For then the Spirit instructs man where he will walk and how he will act and man becomes sinless in his movement and in his actions because the Holy Spirit is sinless Who leads and guides him. Man cannot walk justly nor act righteously if the All-omnipotent and All-omniscient Spirit of God does not inform him. Whoever is not led by the Holy Spirit of God is led, either by his own individual spirit or by the evil spirit of the demon. As a result of this he becomes helpless, bitter, remorseful, angry and despondent. We cannot endure the Spirit of God in the fullness as Christ the Lord, but we can receive the Spirit of God as much as needed in order to know where, what and how. According to the purity of the heart, the Holy Spirit settles in the heart and from the heart directs man.
That is why the Church often repeats this prayer to the Holy Spirit: "O Heavenly King, the Comforter, the Spirit of Truth! Come and abide in us."
O God, the Holy Spirit,
