A follower of Christ discovers that "faith passages" are different every year. The faith passages when you are a teenager are quite distinct from the passages through each later decade of life. The stuff that you have angst about now will not matter one, five, or ten years later.
Our Lord is with you and me in every situation, good or bad. We need to be attentive to His Presence throughout everyday. He is there and we are not alone!! Our hope needs to be in Him and not in this world. The world is full of darkness, and we absolutely need to be walking with the Light--Jesus. Our Lord will never make you feel stupid or useless; only people do that. He alone is our Hope, our Comfort, and our Hero in times of distress.
Dearest son, choose your friends wisely. Look for friends that follow Jesus; ones that read the Bible, have a real prayer life, ones that have a "real relationship" with our Lord. These friends are better than gold! These friends will encourage you to live a life for Jesus. Living for Jesus is the only kind of life that is truly worthwhile on this earth.
My son, I lived life apart from Jesus for 29 years. I came to understand what the world has to offer. The world will draw you into its darkness with many, many temptations. There may be happiness for a season, but at the end of these temptations awaits emptiness and devastation. When I lived in devastation, I thought "this is all there is". Then God brought someone to tell me about Jesus. I acknowledged my sin, repented of it, and asked Jesus to be my Lord and Savior. He lifted me out of that darkness and muck. Jesus will always be my Hero!
We all fall short of God's perfect standard for living. The more we try to be good, the more we fail. Salvation has nothing to do with obeying the right set of rules, doing the right type of good works, or feeling a certain way. Salvation comes by simply saying "Yes, Jesus, I trust You". When you accept Jesus' terms for salvation, you can trust that God will honor His agreement forever. Your salvation is secure. The restoration process has begun and God will complete it.
