Love is attachment to an object on account of its goodness. God is the greatest Good, and as such worthy of man's best love. This Good is limited neither by person, time, nor space.
He is self -existent, eternal by nature, and infinite in perfection. He is so excellent that no one outside of God can love Him adequately.
This infinite Good is, besides, the author of every created good. If life, health, friends, and earthly possessions are worthy of man's love, how much more should we form an attachment to God as soon as we learn that He is the eternal, uncreated Good?
God has also been very good to man by extending to him the countless blessings of creation, redemption, and sanctification. He has loved us individually with an everlasting love. He provides for us and watches over us with greater solicitude than the fondest mother ever manifested toward her child. Christ the Lord loved us to that extent that He sacrificed the last drop of His sacred blood for our sake. Wherefore St. John says: '' He loved us to the end " (John xiii, 1). In creating us God fashioned our hearts in such a way that we necessarily love what is good. Will we then be so foolish, so ungrateful, so disobedient as not to love Him, the infinite Good ? He commands us to love Him. “My son,'' He says, “give Me thy heart" (Prov, xxiii. 26). “Thou shalt love the Lord thy God with thy whole heart, and with thy whole soul, and with thy whole mind. This is the greatest and first commandment" (Matt xxii. 37-38).
