To me, then, Scripture is given not only to make us wise unto salvation but also to furnish us thoroughly unto all good works (II Tim. 3:15-17) – even unto the good works of Christian education, Christian medical practice, Christian business activity, Christian farming, Christian housework, and Christian everything-else (Gen. 1:26-28 & Ps. 8). This does not mean that the Bible is a handbook for all of the special sciences. Yet it does mean that the Bible is indeed the Sourcebook for everything. Indeed, no special sciences are to be studied contrarywise to the clear teaching of Scripture.
For although, as the Confession declares (I:6), “there are some circumstances…common to human actions and societies, which are to be ordered by the light of nature and Christian prudence” – this is always to be done “according to the general rules of the Word, which are always to be observed.” Evolutionism, which I previously championed, is therefore not just unacceptable even “for the birds.” It is also not even for the “creeping things.” For God made all of His creatures “after their kind.” Gen. 1:11 f,21f.
Sometimes I am asked about my thoughts on life after death. Here I believe with the Bible (Ps. 51:5 & Eph. 3:3 & John 3:3-5) that, as a result of man's fall, all men are now by nature conceived in iniquity and born in sin – and hence cannot even see (and still less enter into) the Kingdom of God, unless they be born again. Until man is regenerated, he is nothing more than a lost soul under the righteous judgment and wrath of a virtue-loving and sin-hating God (Eph. 2:12 & John 3:36). Unregenerates are thus on their way to eternal separation from God in a place called Hell, where they are to suffer constant agony in body and in soul – for ever. Mark 9:42-49 & Rev. 14:9-11.
Yet I also believe God so loved the world that He gave His only begotten Son, so that whosoever believes in Him should not perish but have everlasting life (John 3:16). Those who believe in Jesus as Lord of their lives, inherit eternal bliss – in three (triune) stages.
First, they receive Christ here and now – and thereby enter into the Kindom of Heaven here on Earth (John 5:24). Second, when they die, their souls go to Heaven – where they enjoy conscious bliss with Jesus until His second coming (Rev. 4:1-11). And third, with Christ's second coming back to this Earth to transform it, He brings Heaven and its inhabitants with Him – so that Heaven then comes down to Earth (Rev. 21:1-2). Then the saved will get back their immortalized bodies, and thenceforth perfectly love God and enjoy Him forever in both soul and body (I Cor. 15:35-58). See here the Catechism, Q. 1.
Meantime, I believe that Christians are to live to God's glory in this world here and now. To me, this means that Christians must be “triunely” involved in three united and related activities all their time.
First, they must subdue the Earth and all its fullness to the glory of God the Father – precisely through serving the Lord in the ordinary practice of their professional careers (Gen. 9:1-6 & I Cor. 10:31). Second, they must evangelize the Earth and christianize all its nations as commanded by God the Son – and get them to obey all things whatsoever He has commanded, even from Genesis through Revelation (Matt. 28:19 & Mark 16:15). And third, they must promote the coming of the Kingdom in all its many facets – with all their might, through the power of God the Spirit, as all history further unfolds toward its divinely-predestinated consummation. Luke 11:2 & Rev. 14:13.
