'Let Us' in the Bible

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

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

But let us not get weary doing that which is good: for in due time we will reap, fainting not.

Then therefore, as we have opportunity, let us do good to all, especially to those who are of the household of faith.
