We do not study the Bible very long before we realize that faith is very important. Therefore it is important for us to find out what faith means.
Faith is personal trust or belief.
We use the word in our everyday talk. We mean that we trust him to make us well. So, in the Bible, faith is personal trust in God. It means that we believe what God says and we trust Him to save us and to keep us. If we look around us in the world, we will realize that some men do not have faith in God and so they are not saved.
