If you stand for something, someone will hate you, of that you can be certain! We are known by our friends and our enemies! Why does Satan hate the church? I can't be certain of all the reasons, but look at the book of 1st Peter for a at least one:1Pe 1:1 Peter, an apostle of Jesus Christ, To those who are elect exiles of the dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia,
1Pe 1:2 according to the foreknowledge of God the Father, in the sanctification of the Spirit, for obedience to Jesus Christ and for sprinkling with his blood: May grace and peace be multiplied to you.
1Pe 1:3 Blessed be the God and Father of our Lord Jesus Christ! According to his great mercy, he has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead,
1Pe 1:4 to an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you,
1Pe 1:5 who by God's power are being guarded through faith for a salvation ready to be revealed in the last time.
1Pe 1:6 In this you rejoice, though now for a little while, if necessary, you have been grieved by various trials,
1Pe 1:7 so that the tested genuineness of your faith--more precious than gold that perishes though it is tested by fire--may be found to result in praise and glory and honor at the revelation of Jesus Christ.
1Pe 1:8 Though you have not seen him, you love him. Though you do not now see him, you believe in him and rejoice with joy that is inexpressible and filled with glory,
1Pe 1:9 obtaining the outcome of your faith, the salvation of your souls.
English Standard Version
Have you ever noticed children playing with their toys at Christmas? They are enjoying themselves and then one of them opens a present which the other one wants. What happens; well, I guess that depends on the kids, but many times there is a fight! I think that is what is going on with Satan; God made a way for us and Satan is jealous; jealous of the blessings given to those who love God, jealous of the hope they have and of the final outcome of their faith. But we shouldn't worry about it, we should live our lives like their contents were plastered all over some bulletin board in a very public place... because they are and the location is in heaven! The question is: Are the contents of your life something that Satan will hate or not?
