Who was the first slave master and slave in the Bible?
My understanding of the day of the Lord as referred to in the Bible with the end times starts after the rapture. These verses suggest that the Day of the Lord starts with different periods in respect to the rapture. Joel  3:31, 1 Thessalonians 5:1-5 and Isaiah 13:9. Can you please explain these verses to me as to when exactly the day of the Lord begins?
Is celebrating birthdays biblically wrong?
I understand the Bible says that God requires a blood sacrifice (Hebrews 9:22). I have heard preachers say that if Jesus had not shed any blood, then his death would not have been a valid sacrifice. Why does God require a blood sacrifice? I know the life of the flesh is in the blood (you can not live without blood), but you can die without bleeding. What is the significance of the blood sacrifice?
Can I get scriptures that support baptism as part of salvation besides Mark 16:16?
