How do we know that God's methods in preaching the gospel are effective?
Answered in 1 source
The effectiveness of gospel preaching is rooted in God's promise that His Word will accomplish its purpose, as seen in Isaiah 55:11.
In Isaiah 55:10-11, the Lord declares that just as rain and snow water the earth and cause it to bring forth fruit, so shall His Word that goes forth out of His mouth not return void. This promise assures us that the means God has ordained for spreading the gospel will bear fruit, even when we cannot see immediate results. Preaching the gospel is a command, and it glorifies God by making His truth known to His chosen people. Each act of casting the seed or sharing the Word operates under the assurance that God prepares hearts to receive it, which is essential in understanding the effectiveness of gospel outreach.
