During the early Christian period, having faith in Jesus as the Savior was the one and only spiritual armament the Jewish exiles had while being scattered by their Roman oppressors. Although they truly believed in Jesus as their Savior, they lived in constant fear while being pushed into a dead end. So, with this as backdrop some Jewish believers started to fall away out of fear, by things being imposed upon them, and by having the absence of true leaders. These believers who fell away stood a high chance of becoming the root of bitterness. Those who fell away while this root of bitterness started to sprout in their hearts, couldn’t help betraying their God and misleading other believers in the wrong way. Some of them would even justify their wickedness by saying, “Although we may have fallen short of the grace of God, we are so fortunate to be alive while living in a foreign country.”
