I hear you about the gospels not lining up. This really bothered me about two years back and I had to wrestle with it quite a bit. It actually happens throughout the bible, I learned this when I first listened to the bible chronologically. I believe that all scripture is breath out by God as we learn in 2 Timothy 3:16, however, I also believe that the bible was written by more than 40 different people, inspired by Holy Ghost.
I have heard it put this way, but I can not remember by who. If me, you and two others go to a party and we all go home the next day and tell people about the party, our accounts will differ slightly. I would probably talk about the delicious stew while you might have focused on the bitter balls This does not mean that either of our accounts are not true. The examples of the ascension are a very good example of this. I do not see any contradiction in this case, but rather different accounts of the same event.
Why can Jesus pay our debt? Now that is the question. That is the core of everything, is it not?
I am doing terrible, remembering my writers today, but one of the old Christian writers refers to this at “The Great Exchange”. You give all your sin to God, past present and future and he gives you his righteousness instead. We see this in Romans 6:10 and Hebrews 7:27. There is a fabulous way of studying the bible called biblical theology. It requires picking a theme and then following it from Genesis to Revelation. If you do this with Blood Sacrifice, it will blow your mind how it all comes together. I am doing this with the temple at the moment. If you decide to discuss the great exchange with your coworkers, this is the gospel that the lost need to hear. As it is once and for all, there is no currency or balance system involved.
As for feeling the Holy Spirit in you. I know what you mean, if you are being called to share the gospel with your coworkers, I would say that you are definitely feeling the Holy Spirit in you, but not as you are expecting to. It is sad to say, but I have gotten so used to Holy Spirit in my life that I do not feel Him anymore also. I need to spend time with Him developing relationship with Him, to know him more. James 4:8 draw near to me and I will draw near to you! This Christian life requires us to live by faith. It is the way He has set it up to be. I find it tough to be honest and am crying out to see Jesus. We are all on the same journey.
