Why is the gospel called the Word of Truth?

In Ephesians 1:13, Paul describes the gospel as the 'Word of Truth' which serves as the basis for our faith and the promise of salvation. This title signifies that the gospel is not just a message but a reliable revelation from God that is rooted in truth. Believers can find security in the promises of Scripture, which are always fulfilled in Christ. This trust in the gospel is foundational, underscoring how Christians view Scripture not just as words, but as the very means God uses to bring about faith and transformation in our lives.
