Does it really matter how many people are in the world the numbers change constantly. What people should focus on is Glorifying God and accepting Christ as their Savior and God will lead you down the narrow path to Heaven. Just think of it this way your best moment on this earth wouldn't compare what so ever to the worst experience in God's presence. ( just figuratively speaking, but say i am wrong i will have strived to be a good person, obviuosly failing at times. If you don't believe in Christ and you pass and are wrong you will get the horrible gift of eternal damnation ( you will be seprated from the presence of God for good.)
