This little booklet by Greg Koukl is outstanding. He categorizes over 100 Scriptures demonstrating how and why Jesus is the only means of salvation that God has provided by which all mankind must be saved. He gives the following nine reasons and then substantiates each reason with various Scriptures.
Reason #1: Jesus Is the Only Source of Salvation for the World
Reason #2: Jesus Is The Father’s Choice
Reason #3: Rejection of Jesus is Rejection of the Father
Reason #4: Rejection of Jesus Brings Judgment and Wrath; Belief in Jesus Rescues from Wrath
Reason #5: Jesus Is the One Who Provides Forgiveness from Sin
Reason #6: Many Imposters Will Claim to Provide Other Ways of Salvation
Reason #7: There Are No Other Alternatives for Salvation
Reason #8: All Nations Are to Be Given the Gospel
Reason #9: Jesus Will Be Man’s Judge on the Final Day
I would recommend this booklet be purchased to give away to both Christians and non-Christians. It is an excellent tool for both evangelism and apologetics. Greg Koukl lets the Scriptures speak fro themselves – and you would be hard-pressed to read all these Scriptures without falling more in love with Jesus, or letting others know how and why they need Jesus to save them from their sins and God’s wrath; and instead be gracious recipients of His abundant mercy and love forever.
