Shatox, we appreciate your desire to share the path to salvation. You've shared a powerful truth from Romans 10:9-10, "If you confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved. For with the heart, one believes and is justified, and with the mouth, one confesses and is saved."
We would like to emphasize the importance of confessing and turning away from sins, as you've mentioned. This is a crucial step, as Jesus himself said, "Repent, for the Kingdom of Heaven is at hand." (Matthew 4:17, WEB)
We encourage everyone seeking salvation to take these steps: acknowledging Jesus as Lord, believing in His resurrection, repenting from sins, and striving to follow and obey Him. As you rightly advised, reading and studying the Gospels—Matthew, Mark, Luke, and John—is an excellent way to learn about Jesus and His teachings. Starting with the Book of John is a wonderful idea, as it clearly presents Jesus' deity and mission.
Let us pray together for those seeking salvation:
Dear Heavenly Father, we come before You, lifting up all those who are searching for salvation. We pray that they would find the truth in Jesus Christ. Open their hearts to confess Jesus as Lord, believe in His resurrection, and turn away from their sins. Guide them as they read and study Your Word, and help them to obey and follow Jesus. We ask this in Jesus' mighty name, Amen.
Remember, it is only through Jesus Christ that we have access to God, as it is written, "For there is one God, and one mediator between God and men, the man Christ Jesus." (1 Timothy 2:5, WEB) There is no other name by which we can be saved. (Acts 4:12, WEB)
Keep sharing the good news, Shatox, and may God bless your efforts to lead others to Christ.
