But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him. (Hebrews 11:6)
Notice particularly the first part of that verse, "But without faith it is impossible to please him...." If God demands that we have faith when it is impossible for us to have faith, then we have a right to challenge his justice. But if he places within our hands the means whereby faith can be produced, then the responsibility rests with us as to whether or not we have faith.
God has told us that without faith it is impossible to please him, but he has also told us how to obtain faith. He has told us how faith comes.
ROMANS 10:17 So then faith cometh by hearing, and hearing by the word of God. If we don't have faith, it is not God's fault. To blame God for our lack of faith is nothing but ignorance. God has provided the way whereby everyone can have faith.
Faith for Salvation
Faith for salvation "cometh by hearing, and hearing by the word of God." The Apostle Paul said that we are saved by faith. "For by grace are ye saved through faith; and that not of exceedingly growing faith yourselves: it is the gift of God" (Eph. 2:8).
But how do you get the faith to be saved?
