Since i m suffering depression
Why are you depressed? Do you know that our Lord Jesus Christ can helpy you conquer and overcome depression.
and feelings keep going up and down,
My feelings go up and down all the time, and have been for 70 years.
a friend just told me: faith is not by feelings.
Yep, that is correct. Faith is well described in Hebrews 11:1, one of the shortest verses, but with so much depth and meaning.
u really need to let feelings go.
Feelings is guilt, shame, offence, resentfulness, anger, bitterness, etc., etc.
So have you worked through all of this by confession, repentance, and forgiveness?
Faith is by the word.
Hebrews 11:1 is a description of what faith will do. By our faith it will prove that what is unseen is actually for real. Those unseen things you don't see now, but will see later on, will boost your faith and take it to another level.
My faith is so high, because of my personal experiences that I have had with our Lord Jesus Christ.
but how to let feelings go?
You confess, and repent them by confessing and repenting your past sins that you haven't done anything about. And begin to forgive all those people who have hurt, offended, abused, and rejected you over the years. And then forgiven yourself.
You will be amazed when you finally do this then those feelings will go, and so will your depression.
I m a human, and it is real hard, it keeps come to bother my minds and my heart my faith.
You have as much faith as you have right now, and your faith will get stronger as you become more complete in our Lord Jesus Christ.
Healing of the brokenheart, being delivered from evil, and being set free from captivity is the beginning of your faith.
