Grant to us, O Lord, not to mind earthly things,
but rather to love heavenly things,
that while all things around us pass away,
we even now may hold fast those things which abide forever.

Grant, Lord, that we not to be anxious about earthly things, but 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.
