On July 26, 2016 in Sagamihara Japan, a young Japanese man went on a stabbing rampage at a facility for the mentally disabled where he had been fired, killing 19 people and injuring 25, in which 20 were listed as serious. This killing carnage took place during a 40 minute time window, when facility staffing was at its minimum.
This is another example that killings will continue in the world, even if all guns were banned and destroyed. The root cause of these vicious and merciless attacks are the harden hearts of all human beings. Evilness will always be in this world because of evil harden hearts, and this evilness will always find a way to kill and maim.
The only solution to this harden heart problem and the evilness that is associated with it, is for all humans to give their lives over to Jesus Christ. If you are willing to accept Jesus Christ into your life as Lord and Savior, your life will start changing to a more positive way. Over time, the evilness that is in the person’s heart will go away.
There is no other full proof and effective solution. All it takes to start this life changing process is to say yes to Christ and no to your sinful ways.
