Jesus Christ had given the disciples two important things, the great law and the great commandments.
1. The Great Law.
We are selfish, loveless and greedy. However, after we know Jesus our life change. We love God with all our heart and our thoughts and we love our neighbors as we love our selves.
2. The Great Commandments
After Jesus was reincarnation and before going to heaven Lord Jesus had commanded His disciples to go out reach or evangelize throughout the world (Matt 28: 19-20) He gave them authority to teach people all over the world to be His disciples.
3. The believers who have great law rule their hearts will love people and would like to encourage them to have God. They got this for free. They feel that they should give for free. There are many examples. (Co 2:6) (Matt 10:5-8) (Rome 1:14) (Acts 2:41-47) (John 4:28)(Matt 18:23-39) (Rome 12:1-8) and (Matt 6:9-10)
