Without a doubt we will have struggles and suffer temptations in this world, and we'll frequently fall prey to Satan's attacks. However, Jesus has prayed and is praying for us, that though we be sifted as wheat as was Peter, God would use that sifting to strengthen our resolve.
God loves you is a fact, but what exactly does it mean that He loves you? Does it mean He would do anything for you to make you happy? Does it mean a qualitative state or quantitative? The fact that He loves means He gave, He sacrificed...for you.
