It is no accident that the word forgive comes from the word give. Jesus taught both principles in conjunction with each other. If you forgive, you will receive forgiveness. If you give, others will also give to you. The spirits of forgiveness and giving are opposite from the spirits of the devil.
People in the world lash out at anyone who mistreats or abuses them. Jesus said, however,"God blesses you who are hated and excluded and mocked and cursed because you are identified with me, the Son of Man. When that happens, rejoice! Yes, leap for joy! For a great reward awaits you in heaven. . .." (Luke 6:22-23). He also encouraged His disciples to love, do good, and pray for those who mistreated them (vv. 27-28). In the same passage He continued, saying, "Give what you have to anyone who asks you for it; and when things are taken away from you, don't try to get them back" (v. 30).
You are called to be God's channel of mercy. He wants to use you to pour His grace and blessing upon the world. You must not block that flow through unforgiveness or stinginess. You must let forgiveness and giving flow. When you do, God will bless you, "full measure, pressed down, shaken together to make room for more, and running over" (Luke 6:38). Give and forgive. "Then your reward from heaven will be very great...." (v. 35).
