Biblical explanation
A contradiction would require two statements that cannot both be true when they refer to the same thing in the same sense and under the same circumstances. Scripture instructs us to handle God's Word carefully rather than drawing conclusions prematurely. Proverbs 18:13 says: "He that answereth a matter before he heareth it, it is folly and shame unto him." Jesus also challenged people who interpreted Scripture incorrectly: "Ye do err, not knowing the scriptures, nor the power of God." Matthew 22:29, KJV Different Gospel writers sometimes emphasize different details. This does not automatically mean that their accounts contradict each other. One witness may record one detail while another records another. For example, one Gospel may mention one person at an event while another gives additional information about other people present. The accounts can complement rather than cancel one another. Scripture does not say that every difficult passage will immediately be easy to understand. Peter even says that some things in Paul's writings are "hard to be understood" (2 Peter 3:16). Therefore, difficulty should not automatically be equated with contradiction. A careful study should consider context, wording, audience, chronology, genre, and the possibility that different writers are describing different aspects of the same event.
Key takeaway
Salvation is entirely by grace through faith in Christ. His atoning sacrifice, heavenly ministry, and intercession are the foundation of assurance; obedience, Sabbath faithfulness, and loving service are the fruit of a redeemed life, never a way to purchase acceptance with God.
