Today's second reading is from 2 Tim 1. Verse 7 reads "For God did not give us a spirit of cowardice but rather of power and love and self-control."
Basically, I see that the Holy Spirit renews us, making us holy. Since it's the guilty person who gets nervous and is timid, a holy one becomes fearless and strong with God on his side. Naturally, the Spirit also makes you loving. Be fearless and loving at the same time ~ this is how we are to deal with others, including our enemies. As for self-control, once the Spirit takes over, we no longer need to exercise it since the Spirit is now in command.
Take full advantage of the gifts that the Holy Spirit gives us.
