What does justification by faith mean?
Jesus paid the debts on the cross for our sins. Faith is to believe this truth. Those who received Jesus as their Savior would get justified by God unconditionally.
It means I don’t need to be something or do something special, but just believe that God exists and that he is a reward for everyone who seeks him.
It means: Not because of what I’ve done, but because of who YOU are. Not because of who I am but because of what YOU’ve done.
Salvation comes from God, is a free grace, not what I can do, is the grace of an unconditional God. Faith is the path to welcome God’s grace and love. As soon as I accept, this salvation will come to me.
