It is a spiritual principle that if you judge you will be judged by others.
It is a spiritual principle that if you forgive you will be forgiven.
It is a spiritual principle that if you create strife, you will receive every evil work in your life.
It is a spiritual principle that when you are merciful that you will obtain mercy.
It is a spiritual principle that you should do to others as you would have them do to you, because they certainly will.
It is a spiritual principle that if you sow to righteousness that you will inherit righteousness.
It is a spiritual principle that is you sow to the flesh (the works of the devil) that you will reap destruction.
Spiritual principles are spiritual truths. They were taught by Jesus and others so that you will understand the truths relating to seed sowing and reaping. Jesus taught that truth extensively in an effort to teach all of My children that your joy and happiness and comfort in life depend upon your thoughts, attitudes and actions towards others.
Protect yourself, your family and your earth by always quickly forgiving others, being merciful to others, never judging others, sowing peace and love in every endeavor. In other words, sow seeds into My kingdom of righteousness and you will always receive righteousness engulfing you.
I would call them simple principles. They are easy to follow when you are led by My Spirit. He will only lead you into still waters and green pastures.
Matthew 5, 6 and 7; Galatians 5:7-10.
