regarding lucifer:
yes that's right. actually he used to be the most beautiful of God's creations. his task was to lead worship in heaven. but then he got proud and thought to himself he could be equal with God. i think sa Isaiah nakalagay yung sinabi nya na "i will ascent to the throne of the Most High(not exact words, something siilar to that)".
i heard a pastor share a vision of creation of the universe. in the vision, lucifer lead all heaven in worshipping God, worship got higher and higher, more intense. then the Lord started to create our known universe. stars started to form, galaxies forming the universe. well, lucifer thought it was because of his leading the worship that caused the creation. thats when he started to be proud.
for me its such a warning to us para hind maging proud. i think its such a great temptation to worship leaders, leaders n general to get proud. kung si lucifer nga naging proud when he was always beholding the glory of God sa heaven, pano pa kaya tayo that we haven't even seen a glimpse of His glory.
maiba ako, i desire to see how worship in heaven goes. i could only imagine its must be so glorious. i know a pastor that God allowed to see a glimpse of heaven and hell. sabi nya glorious daw talaga ang heaven. nothing on earth could come close. kaingit naman sya, Lord ako din.
