Rededication

My time is coming up soon and I am afraid because I haven’t really done much for the kingdom. I am not the worst person in the world, but definitely nowhere near the best or a great person. I accepted Jesus as my Savior when I was a child but never did much by way of spreading the gospel because Christianity already has such a bad reputation. I just tried to be an all-around accepting and decent person. I spent a lot of my work time doing things for the betterment of humanity, namely research on treating diseases. But outside of work, I mainly tried to focus on enjoying life with friends and family. I didn’t do much volunteering in my lifetime, never really gave to the poor, etc. I also struggled with sin and at one point started referring to myself as agnostic because I was mad at God and just wasn’t convinced in Christianity. However, as my time approaches, I still can’t shake my belief that God exists, but I’m wondering if my salvation has been revoked. If I need to rededicate what little life I have remaining to God, what would it look like to be in right-standing with Him? I don’t have money to donate, nor do I come across anyone that would need salvation. I just want to live eternally with God. I know this is an overall selfish desire. But life hasn’t been great and I’m just looking for a peaceful existence filled with love and joy after I go.
