Do you have a hard time receiving the Gospel because you know the people trying to bring it to you too well? You know they’re not perfect. You’ve seen the mistakes they’ve made, the sins they’ve committed - even though they call themselves Christians, and so you haven’t been able to bring yourself to listen to them when they’ve tried to tell you about the Gospel.
The real problem is not with them, though; it is with your heart. The message they bring is the only thing that can save you from eternal punishment. Stop looking for excuses not to listen to the Gospel. Stop criticizing the messenger and instead listen to the message. Trust Jesus and be safe.
