'Let Us' in the Bible

If we live in the Spirit, let us also walk in the Spirit.

Let us not be desirous of vain glory, provoking one another, envying one another.

Let us not be weary of well doing; for in due season we shall reap if we faint not.

As we have opportunity, therefore, let us do good to all, but especially to the members of the family of the faith.
