Have Faith of a Mustard Seed. This Mustard Seed Faith design is to remind you to NEVER give up. Keep your faith and keep moving forward. Do no back down, do not give up! No matter what people tell you. God's word says in Luke 17:5-6 - The apostles said to the Lord, “Increase our faith!” He replied, “If you have faith as small as a mustard seed, you can say to this mulberry tree, ‘Be uprooted and planted in the sea,’ and it will obey you."
