Jesus did talk about tithing as shown in Matthew 23: 23 and Luke 11: 42, but these verses cannot be quoted in our day to encourage Christians to tithe because it was not His intentional message. Although Jesus did not condemn tithing here, we must understand Jesus was still under the Old Covenant as the New Covenant began with His death and resurrection.
Do Non-Christians Have Free Will?
This is exactly what has happened to humanity through sin. The human free will is biased toward evil. It really exists, and really can make decisions – just as the loaded scales still work. But instead of giving a balanced judgment, a serious bias exists toward evil. Therefore, human free will really exists in sinners, but that it is compromised by sin.
