One should give their all to God because He’s the only one who should get your all, as Jesus told us in the Gospels. The first and greatest commandment.
Matthew 22:37
Jesus replied: “ ‘Love the Lord your God with all your heart and with all your soul and with all your mind.’
Mark 12:30
Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.’
Luke 10:27
He answered: “ ‘Love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind’ ; and, ‘Love your neighbor as yourself.’ “
INDEED.
