Hi Tilda!
I've only just seen your post and you ask some very good questions.
As to why I think God will help me through a problem?
I answer this by saying He has shown His love and compassion for me by coming to this earth in the person of His Son Jesus Christ, and dying for me, offering Himself as perfect sacrifice, so that I may have life and have it more abundantly.
"Greater love has no one than this, than to lay one's life for his friends."
John 15:13
Why do we suffer?
It is the result of sin which tainted God's creation including our bodies. However, Jesus came to redeem mankind, that is to save us from the penalty of sin, which is spiritual death and separation from God, and from the power of sin, which can enable us to turn from sinful, selfish desires that can never completly satisfy, to experiencing a life full of peace and joy.
How does man experience this redemption?
It is by faith in the Son of God, Jesus Christ.
"for all have sinned and fall short of the glory of God"
Romans3:23
"But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us."
Romans 5:8
"For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord."
Romans 6:23
"that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved"
Romans 10:9
"For "WHOEVER WILL CALL ON THE NAME OF THE LORD WILL BE SAVED."
Romans 10:5
