Predestination, Chosen, Whosoever Will?

Historically, Christians have wondered what God's Holy Word, the Bible, is saying, when it says in Ephesians 1:4-5a, …he hath chosen us in him before the foundation of the world… Having predestinated us… Many have said that this means God exclusively chose and predestinated certain people to be saved and all others would be lost and go to hell. This has upset many, many Christians. Often, in frustration, they have said, "How can God be a loving God and create only some people to be predestinated to go to Heaven?" Others have said, "Well I read in 2 Peter 3:9, The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to usward, not willing that any should perish, but that all should come to repentance. When we don't understand the Word of God, it is not the Bible that has the problem, it is us. If we keep searching and praying, God can and will clear it up. You will see Predestination, Chosen, and Whosoever Will as one clearly taught doctrine.
