Faith

Faith is a force.  The Bible says that your faith, even faith the size of an almost invisible mustard seed (Matthew 17:20), is sufficient to move mountains.  As we can push and move things in the physical dimension, so faith pushes and moves things in the spirit world (dimension).  Great faith operates like a bulldozer or crane does in the physical dimension.  If it is big enough, obstacles are removed.

Faith is a conduit.  Faith is a passageway between the spirit and physical worlds.  The things (and works) of God that exist in the spirit world manifest in the physical by your faith in them.  Your faith is the channel that allows spirit things to manifest in your physical world.  Faith also is the interface where God moves on your behalf.

Faith, authority and actions.  Earlier I wrote that you have authority over Satan and his power.  Luke 10:17 and 19, respectively, say: "Then the seventy returned with joy, saying, 'Lord, even the demons are subject to us in your name'" and "Behold, I give you the authority to trample on serpents and scorpions, and over all the power of the enemy, and nothing shall by any means hurt you."  Matthew 18:18 says:  "Assuredly, I say to you, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed (let loose) in heaven."  Faith is your enabler; through faith you believe what He says; with it you exercise the authority that God has given you through Christ.  Through faith you take actions.  By faith you continue doing whatever "it" is until the results manifest, until they become solid and secure for you (i.e. you believe that your existence in God is as He says it is).  See Hebrews, chapter 11 regarding faith as an enabler.

Forgive

You and I are commanded to forgive.  When we receive God's forgiveness we lose the "right" not to forgive (anyone - even ourselves!).  If you don't forgive, God will allow you to remain in bondage until you do; the provision of freedom through the cross will be withheld until you forgive.  Matthew 18:32-35 discusses this.

As a parenthetical comment:  in order to forgive you may have to come to the understanding that God will replace what was taken, and also that forgiveness does not serve as an enabler.  Somehow God will free you even is you forgive!

God, through immense cost to Himself (the death on the cross of His only begotten Son), forgives you;  He expects you to do the same for others.  If you do not or seemingly cannot, you'll remain on the outskirts of God's Kingdom and blessings.  Oh you'll be looked in on constantly, but the decision to forgive remains yours.  T His is one "thing" God cannot do for you.  No matter how difficult it may be to let go and let God handle the justice part of the equation, you can do it through Jesus.  Forgiveness is a work inside your heart and spirit-and yes, it can be hard work!
