Luke 17:5 And the apostles said to the Lord, “Increase our faith.”
As the apostles grew with the Lord they realised how much more they needed to learn and how much they needed to exercise their faith as well – hence asking for greater faith.
We all do have our doubts which the evil one will try to play upon, but we all have faith as well. That faith, no matter how small, makes a huge difference!
God wants us to know that no matter how little faith we may think we have, we always can come to Him for more because He always wants to love and support us – as long as we will let Him!
