Therefore our concern now must be to be grateful to the Father of all mercy and consolation and see to it that our faith henceforth does not consist in words but in power. For St. Paul says in 1 Corinthians, "The kingdom of God does not consist in talk but in power." Our ability to speak or write eloquently about it is not sufficient; rather must our lives and our deeds testify to the truth, as we demonstrate our love and bestow our works of kindness on friend and foe.
Thus we must pray first of all that God may impart more and more strength to us and our friends and let His dear child Jesus grow in our hearts from day to day that we may praise, glorify and confess Him with a zealous and happy heart.
