Just so you hear a different side of this issue, I do NOT listen to radio/TV or internet preachers. I have been a Christian for 36 years, and I read the Bible and scholarly books. I used to read devotionals, but God moved me on from that. Oh yes, I listen to a good sermon every Sunday morning in my church.
My advice is be extremely careful with who you listen to. Everyone is going to try and convince you what to believe. Look at the division just in this thread! Keep reading your Bible, and pray for The Holy Spirit to lead and guide you. Sometimes, that might mean listening to different preachers. Other times, it might be through a book. And certainly you should be involved in a local church if possible! (I don't recognize your flag, and you may be somewhere without a Christian church.)
