Faith is biblical and therefore does not change with times. It is a freely God given virtue that is open for use by any living person. Receive it from God at no cost.
Before I define what faith is, I want to start by confirming that faith is real and it works exactly as the bible says. Those that practice faith are pleasing to God (Hebrews 11:6) and they reap the benefits of practicing it. I personally have found faith to be working for me and to my experience; it requires one to make an effort. That is why the Bible says that faith without works is dead (James 2:17). The Bible gives us examples of people that combined faith with their effort to realise what they hoped for. Hebrews 11:17 – 31 give details on what Abraham, Isaac, Jacob, Moses, the children of Israel and Rahab did by faith to achieve their intended goals.
