I believe that I am forgiven of my sins by the blood of Jesus and that this was a gift of grace from God because I don’t deserve it. I also am acutely aware that we are not saved by works nor can we maintain salvation through works because Jesus paid the price once and for all, completely. That said, I have a compulsion to tell other people when I can about salvation through Jesus and the fulfillment of prophecy concerning Him and the end times. How do I discern whether what I feel compelled to is of the Lord Jesus or just human works? Should I stop what I am doing? The idea of being left behind after the rapture has led me to tears.
The only qualification for going in the Rapture is belief in the Lord and His completed work on the cross (John 14:1-3, 1 Thes 4:16-17). Any rewards we have earned due to our works will be given to us in Heaven where we’ll fully understand and agree with the Lord’s judgment. There will be no shame or sorrow associated with that judgment, and even if we have nothing to show for our Christian life here, we’ll still be saved (1 Cor. 3:10-15).
If you’re sharing the salvation message and the fulfillment of prophecy associated with the Lord’s first coming with others, you’re fulfilling one of the Church’s primary functions. If you feel compelled to do this, I think it’s a pretty safe assumption that you’re in the Lord’s will.
