Hell is a holding place, a prison. Faith is belief, as you said. Well, there are a lot of things in the bible to believe. You believe there is one God, you do well. The devils believe and tremble. You believe that Jesus paid the price for your sins by shedding His precious blood on the cross, you get eternal life. You believe that he not only paid the price for your sins, but he also died to give you power to overcome sin in this life? Then walk like you believe it. Faith without works is dead. Christians spiritualize faith into some magic power that encompasses all situations and floats us into the kingdom without having to deny our flesh.
Christ told us to pick up a cross and follow Him. He didn't tell us to do this to be saved in eternity. Thats a gift. He said if we love Him, keep His commandments. He didn't say to do this to be saved, thats by faith alone, not of works. Before we were born again, we could not do anything to please God. We were not even 'alive', how could we expect to do good works? God has given us the gift of life, and now we are to suffer for Him in this life, in order to obtain a glorious inheritance it in the next.
Mark 10
29 And Jesus answered and said, Verily I say unto you, There is no man that hath left house, or brethren, or sisters, or father, or mother, or wife, or children, or lands, for my sake, and the gospel's,
30 But he shall receive an hundredfold now in this time, houses, and brethren, and sisters, and mothers, and children, and lands, with persecutions; and in the world to come eternal life.
Luke 18
29 And he said unto them, Verily I say unto you, There is no man that hath left house, or parents, or brethren, or wife, or children, for the kingdom of God's sake,
30 Who shall not receive manifold more in this present time, and in the world to come life everlasting.
The world to come is the thousand year kingdom. Eternity starts after that, on the last day.
John 6:40
And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
