The Christian worldview is no more a leap of faith than its opposite worldview of “humanism” (self separated from God). The self separated from God also has to live by what he/she believes to be true. We all live and make choices based on what we believe. We all live by faith…what and who we believe and trust.
If I am an atheist, I live by my own standard of right and wrong or by some other imposed man-made standard. If I am a New Age believer, I have faith that I will find fulfillment and purpose when I look inside myself. If I am a religious Catholic, I have faith that I will find salvation by following the rules of Catholicism. Scripturally, if I am a true Christian, I have faith that I will find fulfillment and purpose when I look to Jesus, “the author and finisher of my faith” (Hebrews 12:2).
Applying what I believe is faith. Faith without corresponding actions is dead faith (James 2:17-26). If I say I am a Christian, but my actions are worldly, then that is dead faith, not working faith. It is dead because I am not living what I say I believe. The justified (just as if I never sinned) follower of Jesus should live by faith (Habakkuk 2:4, Romans 1:17, Galatians 2:20, Galatians 3: 11-12, Hebrews 10:38). We cannot just believe Father, Jesus, and Holy Spirit exist. We must live by our faith and trust in Him by following Him.
Without that true faith, it is impossible to please Him (Hebrews 11:6). The purpose of faith is not just to choose a doctrine. His purpose is for relationship and fellowship. We are to choose Jesus that we might be saved into relationship with Father and Holy Spirit as well. We are to have faith and trust in Him so that our actions correspond in life to that relationship. That is living faith.
How will we know what actions are truly following Him and pleasing to Him? When we first determine to make Jesus our Savior and Lord in true relationship, He sends us the Holy Spirit to help us (Ephesians 1:13). The Holy Spirit will lead and teach us. He convicts (gives convictions) about sin, righteousness, and judgment (John 16:8). He teaches us and reminds us of God’s commands/ His Word ( John 14: 15-31).
He has also given us His Word of Truth in written form in the Bible. It has been called the “instruction manual” for the Christian life. Psalm 119 informs us of all the benefits of putting His Word in our mind and heart…and lived out in life.
Everyone needs to “leap out” or “step out” in faith in order to do anything…just in order to live. What do you believe so strongly that you are willing to live by it?
