Luke 17:5-6 And the apostles said unto the Lord, Increase our faith. And the Lord said, If ye had faith as a grain of mustard seed, ye might say unto this sycamine tree, Be thou plucked up by the root, and be thou planted in the sea; and it should obey you.
There are times in our lives when we might think, “If I only had more faith!”
2 Thessalonians 1:3 We are bound to thank God always for you, brethren, as it is meet, because that your faith groweth exceedingly, and the charity of every one of you all toward each other aboundeth;
Confusion arises in the assumption that increase equals growth. The mistake is in the understanding of what faith is and how it acts. Jesus answers the apostles about their request for increased faith in an indirect manner. If faith is one grain, it is sufficient to perform the will of God in powerful ways, you don’t need a second grain of faith.
Romans 12:3c God hath dealt to every man the measure of faith.
God gives out faith by measure, not equally. You will never get more faith than what you are given. Rather than thinking of faith as something that can be multiplied, think of it as a muscle group. Some muscle groups consist of more than one muscle. Exercise that muscle group, they do not grow in numbers, they grow in strength.
Romans 16:26 But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith:
Exercise your faith.
