The Balance of Faith and Love

Based on the quoted fragments, one can conclude that for a fulfilling existence, a person needs both faith in God and love manifested through interpersonal relationships. One source emphasizes the importance of love for salvation and true self-affirmation:
"But even demons believe and tremble – one faith is not enough, without love there can be no salvation..." (source: link txt, page: 3019-3020).

Another fragment highlights the inherent human need for communication and closeness with others:
"And man needs love. That is why he searches for a place to turn, for whose shoulder to lean on. Together, things are better, easier. Therefore, the Lord, knowing our weakness, even when He created Adam, looked upon him and said: 'It is not good for man to be alone; we shall make him a helper...'" (source: link txt, page: 754-755).

Thus, according to the cited passages, faith in God is the foundation; however, it does not cancel out the importance of human love and communication. Faith without love turns out to be insufficient for the full realization of human potential, while having a close companion helps satisfy the innate need for emotional support and mutual assistance.
