did god make us to praise him or something? so that more people would follow him?
God made mankind to have relationship with us. He delights in us and loves us so much, that when sin entered the world, He gave us His Son. Its up to us what we do with that Truth. If one decides to accept the free gift of salvation that Christ makes possible, we are compelled to praise God, because we understand just a little bit of what He has done for us and what our sinful state cost Him.
Its His will that none should perish, but leaves it up to each person what they will choose. Of course, He wishes more and more and more would understand how much He loves them and that they would follow HIm! :)
