Love of God is a part of faith. This has been a part of the teachings of many revealed religions. For example, in the Bible, it is stated in both the Old Testament as well as in the New Testament that:
‘You shall love the Lord your God with all your heart, with all your soul and with all your mind.’ (Matthew, 22:37; Deuteronomy, 6:5)
Love of God is not something mysterious. It is the highest degree of acknowledgment of God. When a person discovers God, when he becomes consciously aware of God’s blessings, when he realizes that his existence and entire life are replete with God’s blessings, at that moment a strong affection wells up within his heart. This strong affection is called love of God.
To love God is to love the Sustainer of the heavens and the earth. Such a love is not only an emotional relationship. It brings about a revolution within the human personality. Love of God produces many elevated human qualities, for example, positive thinking, well-wishing for others, trust, courage, etc.
Love in relation to God, is the highest degree of discovery and with reference to man it means developing human-friendly behaviour. Calling people to God is also a manifestation of love of God.
When anyone establishes a relationship with God which is imbued with love, he naturally has a strong urge to convey the message of God to his people, so that none of God’s servants are deprived of the eternal mercy of their Lord.
