Here are the verses that this art came from. Often the mustard seed, verse 6 is focused on. But this time, verse 5 stood out to me. We can never stop increasing our faith. Never. It can never be too big–it may start out small, but we can never ignore it, let it become stagnant, become comfortable in it. We need it to always increase. Always.
Luke 17English Standard Version (ESV)
Temptations to Sin
17 And he said to his disciples, “Temptations to sin[a] are sure to come, but woe to the one through whom they come! 2 It would be better for him if a millstone were hung around his neck and he were cast into the sea than that he should cause one of these little ones to sin.[b] 3 Pay attention to yourselves! If your brother sins, rebuke him, and if he repents, forgive him, 4 and if he sins against you seven times in the day, and turns to you seven times, saying, ‘I repent,’ you must forgive him.”
Increase Our Faith
5 The apostles said to the Lord, “Increase our faith!” 6 And the Lord said, “If you had faith like a grain of mustard seed, you could say to this mulberry tree, ‘Be uprooted and planted in the sea,’ and it would obey you.
