A collect is widely used in many denominations as a way of praying together a common thought. Here is the collect for the week from the Book of Common Prayer.

Grant us, O Lord, to trust in you with all our hearts; for, as you always resist the proud who confide in their own strength, so you never forsake those who make their boast of your mercy; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, now and forever. And all the people said…AMEN.

Notice the strong promises of “always resist” and “never forsake”. Trusting means moving ahead when the way is not evident. Trust in the Christian context is always in a person, namely the Father, Son and Holy Spirit. And we trust that God will act in ways that always lead to the common good. So we place our lives in his mercy instead of our strength.
