“Have a little faith,” people will say, but what does it mean? If we look at the world, it tells us to believe WE can do it—to have faith in ourselves. This is contrary to what the Bible teaches, and the Bible is the source of our faith. Read Romans 10:17--faith comes by hearing, hearing the word.
God loves the married and single Christian equally. He gives them what they need and sustains them through all walks of life. He is not withholding any good thing from anyone because they haven’t done enough.
