Continuing steadfastly in prayer

"Believers in Christ are commanded to continue steadfastly in prayer; and if we don't, we are disobeying God. The Christian who doesn't spend much time in prayer, is disobeying God, just as much as the man who steals, or commits adultery, or murders. The same God who said: 'Thou shalt not commit adultery, thou shalt not steal,' also said: 'Continue steadfastly in prayer.'"””R. A. Torrey
