The world can be overwhelming if we try to take it on by ourselves. Faith is the greatest weapon against the world. 1 John 2:15-16 says this about the world; Do not love the world or anything in the world. If anyone loves the world, love for the Father is not in them. For everything in the world—the lust of the flesh, the lust of the eyes, and the pride of life—comes not from the Father but from the world. Have faith in Jesus Christ who has set you free from the bondage of sin. It is a gift that you have to receive.
For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God—Ephesian 2:8
