Why is being useful to God important?

The importance of being useful to God stems from the transformative work He does in the hearts of believers. In 2 Timothy 2:21, believers are encouraged to cleanse themselves for honorable use, which highlights that a life devoted to God works in alignment with His purposes. When believers are sanctified and made useful, they reflect Christ's character and advance His Kingdom through their actions. The sermon asserts that fruitfulness in good works is evidence of a genuine faith and a heart made alive in Christ, fulfilling God's calling for each believer.
