harden your hearts

The texts from the Roman Catholic Lectionary today offer comment on the decision not to trust the relationship we have with God and the fruit of being open to the prompting of the Spirit to explain and proclaim the truth which is present to us. Aaron and Moses are chastised by God for lacking the trust in Providence to carry them through the complaints and grumbling of the Israelites in the wilderness. The psalmist pleas for the grace of people to be open to the resonance between the Spirit of God and our spirit. Matthew relates the openness of Peter to the revelation of the nature of Jesus. Later,   In this Gospel passage, Peter moves back, as we do, to using our perception without the assistance of our link through the Spirit to make decisions about situations. We harden our hearts.
