Biblical Studies/Christianity/Justification, salvation and grace

Looking at salvation by grace through faith which is not of our works but God who did it for us as a human race .Ephesians 2:8 and 9 adds on and says that none should boast because we do not save ourself except for the grace of God. Our part is to use faith to take what is ours (salvation), we do not deserve to perish , the fire in hell is been made for the devil and his angels from the beginning of all wars that are heavenly. Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels: Mathew 25vs 41.Faith is our part to play believing in what you have never seen but you are convicted of its existence. The world was created by faith by Him from whom all things began.
