With faith all things are possible through Christ. What about the times when things are too big for us? When things are out of the control of human beings we rely on God to do what we cannot do.
If our faith is weak, it’s perfectly ok to ask for more. God welcomes us with much delight to come into His arms asking Him to do what we cannot. It is a step of faith to trust God. It is an honor to God for us to ask Him for more faith which will allow Him to do more.
Mark 9:23-24 Living Bible
“If I can?” Jesus asked. “Anything is possible if you have faith.” The father instantly replied, “I do have faith; oh, help me to have more!”
