If a person is rejecting salvation then the sooner he dies, the shorter his time in the eternal fire will be. The sacrifice of these people proves His love. It seems cruel, but it is necessary to save his life. God with a broken heart destroys some that He may save some. For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.
Electricity is a blessing.
It gives light, heat etc. It is the nearest thing to life we know. But if we break it's laws it is death. We cannot help being born with a sinful human nature because of Adam's sin, but we can help continuing in it. For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins, But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.
