Romans 15:4 For whatsoever things were written aforetime were written for our learning, that we through patience and comfort of the scriptures might have hope.

Notice it says "through patience and comfort of the scriptures. The scriptures are where patience comes from. Patience is simply faith applied over a prolonged period of time. Instead of a momentary faith, patience is prolonged, enduring faith. Patience is when you just believe and keep believing. Romans 15:4 says that patience comes through the scriptures. Romans 10:17 So then faith cometh by hearing and hearing by the word of God. Just as patience comes through the word so does faith. They are also both fruit of the spirit. Galatians 5:22 But the fruit of the Spirit is longsuffering (patience)....faith. When we were born again God gave us faith and patience. They are fruit of your brand new spirit causing you to endure whatever challenges that life brings your way.
