What is a Christian? 2

Answer 2 offers the nearest version of Rev.21:4.
Answer 4 is also Biblical, while Answer 1 is from Winston Churchill and Answer 3 from Shakespeare.
John does his best to describe, with his limited human vocabulary, what Heaven will be like; but it seems to be so wonderfully different that only ever being there oneself would enable anyone to find out.

This is the nub of a very famous passage from Paul's letter to the believers in Rome (Romans 13:6), and widely read as a scriptural Lesson at wedding ceremonies. Beyond the Gospels and Acts of the Apostles, apart from Revelation the remainder of the New Testament consists of commentary and correspondence between early believers, principally Paul after his remarkable conversion.

Jesus may have made some others of these claims, or others fairly startlingly like them, but Answer 1 is the usual version of John 14:6. There are seven such 'I am' claims in John's Gospel.

Most Christians may well believe in the coming of the Kingdom ~ but it has no place, as such, within the formulation of the Creed.

Passover (still celebrated by observant Jews, well over 3000 years or 100+ generations since the original event) marks the deliverance of 'God's chosen people' from slavery in Egypt. They had to be ready to leave on a moment's signal, which meant there was not time tor bread to be left to rise normally, hence its preparation without leaven (yeast). Jesus was at least heavily implying that His own imminent bodily self-sacrifice would open the way for a new kind of freedom (from death, sin etc) to His followers. There may well be further implicit harkback to the flaky nature of the 'manna' on which the Israelites were fed during their trek through the desert ('bread of/from Heaven'). Meanwhile, several churches mark Maundy Thursday with a very special and atmospheric evening service, that combines communion with a shared meal along Old Testament / Passover lines.

The Crucifixion and deposition were over by late afternoon on the Friday, and with the Jewish Sabbath due to start at sunset, the burial had to be fairly hasty. We are told that the womenfolk were unable to complete their last rites before sundown; which is why, in turn, they made their way to the tomb shortly after dawn on the Sunday to carry on and complete these. Bearing in mind that we are dealing with the 'far end of the Mediterranean' at around the time of the spring equinox, the timespan from Jesus' burial to 'the third day' discovery of the Resurrection would have been around 36 hours maximum.

The wind, emblematic of the 'breath of new life', was the first form in which they perceived anything abnormal happening.

The other criminal had teased (if that's quite the word, in their extreme circumstances) Jesus about rescuing Himself and all of them, if He had the supernatural powers and inclination to do so. The other offender rejoined that 'We are up here deservedly, yet He has done nothing wrong', to which Jesus responded 'Today you will be with me in paradise'. (I.e. this offender had recognised and expressed his own guilt, and as such deserved rewarding.)

The reference at Answer 4 is 'only' recorded as the flashing of a bright light ~ a relatively standard symbol of God's presence (cf. 'Let there be light' at the outset of Genesis; Noah's rainbow [involving sunlight through the rain, as we now understand], the Burning Bush, the Prophets of Baal, and several other 'theophanies') ~ plus the voice of Jesus; but not His bodily presence as such. (He had Ascended into Heaven by the time of this encounter, anyway ...)

Peter's denial was poignant, disappointing and probably characteristic (though who are we, to blame him?), but not ultimately causal in the same clear sense as the other people's words and actions were.
