To WackBob and others with similar questions,
Seeking the advice of others who are Christ-followers, for answers to the questions that you have is a wise thing, but let me also encourage you to do something that I feel is even wiser: seek God Himself for the answers to your questions. With your question about whether you should listen to Led Zep or anything else in life, God will reveal Himself and His will, through His Word (The Holy Bible) and through prayer to Him. Go to God in prayer and ask Him your very same question that you are asking others. Pray that He will guide you as you read His Word, for guidance through the decisions you are trying to make. As believers in Jesus Christ, who have received His free gift of salvation and have faith that He is our Lord and Savior whom died on the cross for our sins and rose again, we have the amazing blessing and privilage to go to God and ask of Him ourselves. The answer may not always be what we expect, but I can tell you from personal experience, when I pray to God and seek Him and His Truths in His Word, He always lovingly guides me and provides me with the strength I need. I will pray for you about your decisions and your relationship with God, even though I don’t know you. God calls us to do such things out of the love that He supplies us. To God Be The Glory! Have a wonderful week!
