My whole Christian experience has been clouded with confusion and doubt. I ran across a Christian book, and the title isn't important, but in one side paragraph it said, "This does not mean that Christ's work is effective for everyone, because not everyone is in union with Him. We are united to Christ by faith - that is, by trusting Him as our Savior. But the moment we trust in Christ, we become partakers of and beneficiaries of all that He did in both His life and death." The rest of the book means nothing to me if I don't have first the faith to trust Jesus as my savior. The rest of the book was about how Christians use the gospel for living. Simply put, I don't know if I've ever had genuine faith. I may have. But I don't know. Maybe I'm psyching myself out, and I'm making the simple things hard to understand. Do I put what trust I have into Christ? Yes. Is it very calm, and confident? No. Is it very much at all? No. I've been suffering a lot recently, longing to see God's Kingdom in my heart, and I feel like I hit a brick wall. Do most people who know they trust in Christ know all the time, or does questioning come to mind? If anybody has some advice for me, please share it.
