5 And the apostles said to the Lord, “Increase our faith.” 6 So the Lord said, “If you have faith as a mustard seed, you can say to this mulberry tree, ‘Be pulled up by the roots and be planted in the sea,’ and it would obey you.” (Luke 17:5–6, NKJV)
The apostles understood they would need faith to forgive others and avoid being offenses (Lk. 17:1-4). Their request for Jesus to increase their faith did not go unanswered. The Lord explained to them how to increase in faith (Lk. 17:6-10). Please note, the Lord did not promise to send them an “enabling grace” to empower them with the ability to believe. Since faith comes by hearing, and hearing God comes from His word, we can expect our faith to increase as we rely on His word to lead us (Rom. 10:17). We must trust the power of faith for our faith to increase (v. 6). We must practice our faith, trusting God’s will is fulfilled in us as we put our faith into action (Phil. 2:12-13). Little faith can accomplish great things because Christ dwells in our hearts through faith (Eph. 3:17-20). We devote ourselves to the power of faith when we obey His word. Jesus said, “If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him” (John 14:23). To increase in faith, use your present faith to do what Christ commands. In the context of this passage, that means start forgiving the way Jesus said to forgive (Lk. 17:3-4). Faith activates our obedience, showing we trust the power of faith.
