How do we know Christ provides everything we need?

Philippians 4:19 reassures us that 'my God shall supply all your need according to his riches in glory by Christ Jesus.' This promise highlights that our needs, both spiritual and temporal, are met through the abundant resources found in Christ. Moreover, when we understand that all fullness dwells in Him, as stated in Colossians 1:19, we recognize that Christ is the source and sustainer of our lives. His redemptive work encompasses every aspect, ensuring that believers are fully equipped for every good work in Him.
