This is what God says:
Jesus said to him, “‘You shall love the Lord your God with all your heart, with all your soul, and with all your mind.’ This is the first and great commandment. And the second is like it: ‘You shall love your neighbor as yourself.' On these two commandments hang all the Law and the Prophets.” Matthew 22:37-40 nkjv
Notice nothing about light switches or anything like that. Trying to follow the law will not work only trusting in the Grade of Christ will.
Christians are not under the law:
Therefore, my brethren, you also have become dead to the law through the body of Christ, that you may be married to another—to Him who was raised from the dead, that we should bear fruit to God. For when we were in the flesh, the sinful passions which were aroused by the law were at work in our members to bear fruit to death. But now we have been delivered from the law, having died to what we were held by, so that we should serve in the newness of the Spirit and not in the oldness of the letter. Romans 7:4-6 NKJV Emphasis added
For the law always brings punishment on those who try to obey it. (The only way to avoid breaking the law is to have no law to break!) Romans 7:10 NLT
For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast. Ephesians 2:9 NKJV
Rely on Christ not the works of the law
