“They’re nice people, but they teach loss of salvation.”

Does the Parable of the Soils teach loss of salvation? How can I respond to someone who is always bossing and lecturing me? I want to evangelize on the streets for the rest of my life! Why do I always feel like I’m walking on eggshells with God? I want to launch a fitness program online, but my friends say I need to “do more.” What are your thoughts?
