8240. 'And they believed' means faith and trust. This is clear from the meaning of 'believing' as possessing faith, and also trust since one who possesses faith also possesses trust. Trust is an attribute of love expressed through faith; consequently trust in Jehovah, that is, in the Lord, does not exist except with those in whom love is present, that is to say, love to the Lord and towards the neighbour; for faith does not reside with any others.
