In the Gospel of Luke 21:34-36, we are called to be wary that our hearts do not become drowsy, that we will be vigilant at all times. Jesus calls us to be watchful and to pray for the strength to be what we need to be for God and for all the people of God.
In other words, our faith should be strong and have a firm foundation in Jesus our Lord, and guided by that, all our actions should be oriented to follow Jesus as closely as we can.
