What you do to others is what you also get!

 “Judge not, and you will not be judged; condemn not, and you will not be condemned; forgive, and you will be forgiven; give, and it will be given to you. Good measure, pressed down, shaken together, running over, will be put into your lap. For with the measure you use it will be measured back to you.” (Luke 6:37-38 ESV)

This passage is about things you get back when you do them to others: judging, condemning, forgiving, and giving. Notice that the list has both negative and positive things.

You reap the same thing

“Do not be deceived, God is not mocked; for whatever a man sows, this he will also reap.” (Gal. 6:7 NASB)

“The wicked earns deceptive wages, But he who sows righteousness gets a true reward.” (Prov. 11:17 NASB)

Therefore, do good to others!

“Let us not lose heart in doing good, for in due time we will reap if we do not grow weary.” (Gal. 6:9 NASB)
