Hello, @xplosive. let me add little to what @nextgen622 put down for you.
In the world, there is a choice to choose from which means there are two sides. The side of God and the side of Satan. This world is of Satan ( since when he was cast down to the earth and sin begin to reign) and so suffering and calamities are here and there

"2 Corinthians 4:4 King James Version (KJV)
In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them."

Only those who will/have accepted the love of God (Jesus) will be giving strength to overcome the world not that we will not experience it but we will have what it takes to overcome it.

"John 16:33 King James Version (KJV)
These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world."

also in

"Isaiah 43:2 King James Version (KJV)
When thou passest through the waters, I will be with thee; and through the rivers, they shall not overflow thee: when thou walkest through the fire, thou shalt not be burned; neither shall the flame kindle upon thee."

Which means that when we are facing any problem, it won't overcome us once we are in Christ Jesus which is the Love of God for us.

I hope we have answered you.
Stay blessed.
