Ps 95, 8 Do not harden your hearts

(Ps 95, 8) Do not harden your hearts

[8] Do not harden your hearts as at Meribah, as on the day of Massah in the desert.

(CCC 2659) We learn to pray at certain moments by hearing the Word of the Lord and sharing in his Paschal mystery, but his Spirit is offered us at all times, in the events of each day, to make prayer spring up from us. Jesus' teaching about praying to our Father is in the same vein as his teaching about providence (Cf. Mt 6:11, 34): time is in the Father's hands; it is in the present that we encounter him, not yesterday nor tomorrow, but today: "O that today you would hearken to his voice! Harden not your hearts" (Ps 95:7-8). (CCC 1165) When the Church celebrates the mystery of Christ, there is a word that marks her prayer: "Today!" - a word echoing the prayer her Lord taught her and the call of the Holy Spirit (Cf. Mt 6:11; Heb 3:7- 4:11; Ps 95:7). This "today" of the living God which man is called to enter is "the hour" of Jesus' Passover, which reaches across and underlies all history: Life extends over all beings and fills them with unlimited light; the Orient of orients pervades the universe, and he who was "before the daystar" and before the heavenly bodies, immortal and vast, the great Christ, shines over all beings more brightly than the sun. Therefore a day of long, eternal light is ushered in for us who believe in him, a day which is never blotted out: the mystical Passover (St. Hippolytus, De pasch. 1-2 SCh 27, 117).
