One of the arguments raised in support of abortion is that we can prevent the suffering that comes with disability. In essence, it is better to destroy a child with disabilities than to let him live a life that may include suffering, for himself and for his family.
There are too many people who believe that lie.
Pastor John goes right at that question in Brothers, We Are Not Professionals (emphasis in bold is mine):
5. By judging difficult and even tragic human life as a worse evil than taking life, abortionists contradict the wide-spread Biblical teaching that God loves to show His gracious power through suffering and not just by helping people avoid suffering.
This does not mean we should seek suffering for ourselves or for others. But it does mean that suffering is generally portrayed in the Bible as the necessary and God-ordained, though not God-pleasing plight of this fallen world (Rom. 8:20-25; Ezek. 18:32). It is seen as the necessary portion of all who would enter the kingdom (Acts 14:22; 1 Thess. 3:3-4) and live lives of godliness (2 Tim. 3:12). This suffering is never viewed merely as a tragedy. It is also viewed as a means of growing deep with God and becoming strong in this life (Rom. 5:3-5; James 1:3-4; Heb. 12:3-11; 2 Cor. 1:9; 4:7-12; 12:7-10) and becoming something glorious in the life to come (2 Cor. 4:17; Rom. 8:18).
When abortionists argue that taking life is less evil than the difficulties that will accompany life, they are making themselves wiser than God who teaches us that His grace is capable of stupendous feats of love through the suffering of those who live.
