'And I will shew wonders in heaven above, and signs in the earth beneath; blood, and fire, and vapour of smoke:'
'We see not our signs: there is no more any prophet: neither is there among us any that knoweth how long.'
'And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring;'
'And great earthquakes shall be in divers places, and famines, and pestilences; and fearful sights and great signs shall there be from heaven.'
'Thus saith the Lord, Learn not the way of the heathen, and be not dismayed at the signs of heaven; for the heathen are dismayed at them.'
'And in the morning, It will be foul weather to day: for the sky is red and lowering. O ye hypocrites, ye can discern the face of the sky; but can ye not discern the signs of the times?'
Jesus Christ is God. He is the way out. The only way. Totally free, offered to all that come.
Nobody will be able to say 'I never saw it coming'. Just that they chose to ignore it.
