Collect (ECUSA):

Grant us, Lord, not to be anxious about earthly things, but to love things heavenly; and even now, while we are placed among things that are passing away, to hold fast to those that shall endure; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.

O Lord,
help us not to worry about things.
Help us, instead, to love all beautiful, heavenly things.
Even while we live with our day-to-day problems,
help us to remember what is really important:
the Love and Faith that will be ours for ever
; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.
