The Lord said that we'd still go through valleys, but that He would be there with us. He also promised we'd soar like the eagle. It may seem complicated but, if you put all of your trust(faith) in Him, He will not disappoint... Feelings of guilt and self worth come from a life of sin. We are all sinners but, the good news is that Jesus does forgive if we come to Him with an contrite heart, He will forgive us and remember it no more...
We are the gate keeper to our minds...It is important to have the proper prospective on faith...The Lord said" My people perish for lack of knowledge". The Word of God is there for whomever is willing to take it up...
His Word is full of so many promises and that Word was and still is today very powerful.. How can anyone doubt it?
The Lord helps those who help themselves.
