'Let Us' in the Bible

If we [claim to] live by the [Holy] Spirit, we must also walk by the Spirit [with personal integrity, godly character, and moral courage—our conduct empowered by the Holy Spirit].

We must not become conceited, challenging or provoking one another, envying one another.

Let us not grow weary or become discouraged in doing good, for at the proper time we will reap, if we do not give in.

So then, while we [as individual believers] have the opportunity, let us do good to all people [not only being helpful, but also doing that which promotes their spiritual well-being], and especially [be a blessing] to those of the household of faith (born-again believers).
