How do we know that God's word will not return void?
Answered in 3 sources
God's promise assures us that His word will accomplish its purpose and will not return void, guaranteeing success in His gospel ministry.
The assurance that God's word will not return void stems from multiple scripture passages, including Isaiah 55:11, which declares that as the rain and snow water the earth, so shall His word accomplish that which He pleases. In Mark 4, we see Jesus explaining the various reactions people will have to the gospel; despite this, He assures His disciples that they will be successful in their ministry because of the inherent power of the gospel. God, in His sovereignty, uses the preached word to gather His elect, ensuring that the message reaches those for whom it is intended. Thus, we can have confidence in the efficacy of the gospel as it fulfills God's divine purposes.
