Help! I’m Doubting

Do you view salvation as a tightrope walk across a volcano, with an abyss into which you might fall if you take a misstep? Perhaps your mindset is focused entirely on yourself—your profession and your performance—always checking and double-checking. Is your harness secure? Have you done everything you needed to ensure your salvation? But for all this striving, are you unable to achieve the security for which you long? God wants you to be confident in your salvation. Salvation is a gift from God, but assurance of salvation is also a gift. Learn how your position in Christ provides all the security you need.

If God has united you with His Son, then you can be 100% certain that your problem is 100% solved. You cannot be more secure than when Christ Himself is your harness.

Record impacting statements and write out your answers to the Questions for Reflection at the end of each chapter.

My Tree (Assurance)

Use this simple discipleship tool to get to the heart of your struggle with doubt.

Death in Adam, Life in Christ

See for yourself what Romans 5 teaches about the results of being “in Adam” or “in Christ.”

Who Can Enter into Christ?

This study introduces you to several people whom Jesus sought out—not because of their goodness, but because of His love for sinners. Through this study, behold the Savior who came “to seek and to save the lost.”

Repent and Believe the Gospel

As God helps you identify the cause (or causes) of your uncertainty, He also provides all the wisdom and grace you need to grow and change. This study will help you identify specific steps of repentance and faith you can begin taking, by His grace.

Live True to Your Purpose

Learn more about God’s purpose for saving you. While escaping eternal punishment in hell is a wonderful benefit of salvation, God has a much greater goal for placing you into the life of His Son.

A Plan for Killing Sin

Make a specific plan for killing sin, following the steps outlined in Romans 6: know, reckon, yield.

Practice Believing

Use this study to help identify and reject lies you have “practiced believing” and replace those lies with the truth of God’s Word. You can learn to “think Bible” instead!

The LifeLine mini-books have a long history of biblical faithfulness while clearly explaining how the Scriptures apply to life’s struggles. It is wonderful that this series is now expanding to address issues that teens face. We all know that the issues being faced by today’s teens, their parents and disciplers are very challenging. I’m thankful that these booklets will address the current issues not only with biblical faithfulness but clear biblical, practical application.

— Dr. Ernie Baker

Teens struggle with constantly changing moods, overpowering emotional extremes, identity uncertainty, friendship conflicts, and paralyzing doubts about how God is relevant to their struggles.... These booklets will show not only the sufficiency of the Bible, but also its relevancy for the problems youth face today.

“Unlike the many counseling resources we can find for adults, there are few directly relatable to teens and the issues they face. These mini-books bring the Scriptures to bear in a relevant way for both teens and those ministering to them.”
