"In Him, you also, after listening to the message of truth, the gospel of your salvation - having also believed" (Ephesians 1:13)
The gospel is true because Jesus is true, not simply because Christians believe in Him.
After stating salvation from God's perspective in verse 12, Paul here states it from man's perspective. Faith in Christ is your response to God's elective purpose in your life. Those two truths - God's initiative and man's response - coexist throughout Scripture.
Paul rightly called the gospel "the message of truth" because truth is its predominant characteristic. Salvation was conceived by the God of truth (Psalms 31:5) and purchased by the Son, who is the truth (John 14:6) and is applied by the Spirit of truth (John 16:13). To know it is to know the truth that sets men free (John 8:32). Believers are people of the truth (John 18:37), and they worship God in spirit and in truth (John 4:24) and obey the Word of truth (John 17:17).
Yet, as profound and powerful as God's truth is, people have rejected, neglected, redefined, and opposed it for centuries. Some, like Pilate, cynically deny that truth even exists or that it can be known by men (John 18:38). Others foolishly think that denying truth will somehow make it go away.
Perhaps you've heard someone say, "Jesus may be true for you, but that doesn't mean He has to be true for me." That view assumes that belief somehow determines truth. But just the opposite is the case. Truth determines the validity of one's belief. Believing a lie doesn't make it true. Conversely, failing to believe the truth doesn't make it a lie.
The gospel is true because Jesus is true, not simply because Christians believe in Him. His resurrection proved the truth of His claims and constitutes the objective basis of our faith (Romans 1:4; 1 Peter 1:3).
You will face today armed with the message of truth and empowered by the Spirit of truth. Truth is your protection and strength (Ephesians 6:14). Lost souls desperately need to hear that truth. Represent it well, and proclaim it with boldness.
Suggestions for Prayer: Thank the Lord that by His Spirit He has enabled you to understand His truth (1 Corinthians 2:14-16). Ask for wisdom and boldness to speak His truth in love (Ephesians 4:15).
