Don't worry about it. Matthew 6:27, 33 NIV [27] Can any one of you by worrying add a single hour to your life? [33] But seek first his kingdom and his righteousness, and all these things will be given to you as well. Just know that you are spreading the Good news of Jesus. By spreading the gospel, you are helping God in saving lives. If they reject it, then they miss out, not you. You planted a seed and God will work through more people to bring them in. You live for God, not for the world, so as long as you're on a mission for God, don't let fear stop you. Because God has defeated fear, and he holds the victory. You're just the deliverer. If someone came to you when you were not saved, telling you to follow Jesus, even if you didn't care for it then, in the future, it matters like nothing else when you're saved, and you're eternally greatful for the person God sent to have his will be done.
