Very thought-provoking and timely ....thank you for taking the time to bring up the issue as it gave much food for thought on the matter when it comes to the ways we see fundamentals to the existence of man and how that should cause us to relate to Heaven.
The first one on fasting was very amazing for me to consider when it comes to the issue of fasting, how it connects to developing the mind of Christ and seeing what it means to abstain - for as he noted, we don't fast so we can discipline our bodies...but rather (if I recall how he said it accurately) we fast so that we can discipline our minds/see Christ for who He is.
And on the issue of how the way we treat others prepares us for how we treat Jesus, it is truly amazing to consider how much what we do in this life is a means of actively bringing about the judgment of Jesus to come - or His blessing. The second sermon you posted on Death itself - goodness, that floored me. The way that we really don't know what death is due to how our culture operates - and how Christ shows us what it means to be God due to how he died in his life before us.....and that we defeat death by destroying death. That we cannot know what it means for Christ to have come in the flesh unless we see/understand Christ out of the Flesh.
Again, so thankful for the videos - good things to make you really understand what Christ is about. Shalom sis..
