It is evil to justify killing (unborn babies) by the happy outcome of eternity for the one killed. This same justification could be used to justify killing one-year olds, or any heaven-bound believer for that matter. The Bible asks the question: "Shall we sin that grace may abound?" (Romans 6:1) And: "Shall we do evil that good may come?" (Romans 3:8). In both cases the answer is a resounding NO. It is presumption to step into God's place and try to make the assignments to heaven or to hell. Our duty is to obey God, not to play God.
John PiperThere is a war going on. All talk of a Christian's right to live luxuriously "as a child of the King" in this atmosphere sounds hollow - especially since the King himself is stripped for battle.
John PiperThe suffering of sickness and the suffering of persecution have this in common: they are both intended by Satan for the destruction of our faith, and governed by God for the purifying of our faith... Christ sovereignly accomplishes His loving, purifying purpose, by overruling Satan's destructive attempts. Satan is always aiming to destroy our faith; but Christ magnifies His power in weakness.
John PiperWhy does God bless us with abundance? So we can have enough to live on and then use the rest for all manner of good works that alleviate spiritual and physical misery. Enough for us; abundance for others.
John PiperSuffering in the path of Christian obedience, with joy - because the steadfast love of the Lord is better than life (Psalm 63:3) - is the clearest display of the worth of God in our lives. Therefore, faith-filled suffering is essential in this world for the most intense, authentic worship. When we are most satisfied with God in suffering, he will be most glorified in us in worship. Our problem is not styles of music. Our problem is styles of life. When we embrace more affliction for the worth of Christ, there will be more fruit in the worship of Christ.
John PiperLove is the overflow of joy in God! It is not duty for duty's sake, or right for right's sake. It is not a resolute abandoning of one's own good with a view solely to the good of the other person. It is first a deeply satisfying experience of the fullness of God's grace, and then a doubly satisfying experience of sharing that grace with another person.
