I was raised in a Christian "fundamentalist" house hold.
I had similiar issues when I was young of not feeling I was good enough for God. Our denomination would call it being under "conviction" from God.
I just call it guilt now!
The Lord loves us and if we are his...we cannot be "snatched" from him.
As "Sept. morn." pointed out: Satan cannot have us but since he is the "prince of lies", he will do all in his power to control us by lies, decieption, unfaithfullness, drugs, the occult...etc.[ Ephesians 6 verses 12 thru 20]
Church and fellowship is cool...and we should try to gather together...but I don't place too much emphasis on having to go cause of guilt. I go when I can and feel up to it...but my faith is still between me and the Lord...NOT a church or denomination!
