What does it mean to fulfill our days in Christ?

Fulfilling our days in Christ involves embracing the divine purpose God has for each believer, as articulated in Isaiah 65:20-23, where it is promised that none shall fail to fulfill their days. This fulfillment is tied to our identity as new creations in Christ, wherein every life, whether long or short, finds significance and completion in Him. Therefore, a life spent in service to Christ and His mission brings joy and satisfaction, leading to the assurance that every effort for the gospel yields eternal dividends, reinforcing the value of living in accordance with God's will.
