No, they did not 'saw my legs off'. Several anti-Jn 1:13/3:8 folks have posted recently making no distinction between the heavenly birth and conversion. All three links clearly make that distinction between the two and that one definitely precedes the other. From the SB link:
"James P. Boyce (first president of the Southern Baptist Theological Seminary, in Louisville, Kentucky): "It is not strange, therefore, that they [i.e. regeneration and conversion] are often confounded. Yet, after all, the Scriptures also teach that regeneration is the work of God, changing the heart of man by his sovereign will, while conversion is that act of man turning towards God with the new inclination thus given to his heart" (Abstract of Systematic Theology, p. 374).
John A. Broadus (distinguished professor of New Testament and successor to Boyce at Southern Baptist Theological Seminary): "1. Q. What is meant by the word regeneration? A. Regeneration is God's causing a person to be born again. 9. Q. Does faith come before the new birth? A. No, it is the new heart that truly repents and believes" (taken from Broadus' A Catechism of Bible Teaching, reprinted in A Baptist Treasury, pp. 67-68).
John L. Dagg (first writing Southern Baptist theologian; president of Mercer University in Georgia): "In our natural state we are totally depraved. No inclination to holiness exists in the carnal heart; and no holy act can be performed, or service to God rendered, until the heart is changed. This change, it is the office of the Holy Spirit to effect. . . . But, in his own time and manner, God, the Holy Spirit, makes the word effectual in producing a new affection in the soul: and, when the first movement of love to God exists, the first throb of spiritual life commences" (A Manual of Theology, pp. 277, 279).
B. H. Carroll (founder and first president of Southwestern Baptist Theological Seminary in Fort Worth, Texas): "The true scriptural position [concerning regeneration] is this: There is, first of all, a direct influence of the Holy Spirit on the passive spirit of the sinner, quickening him or making him sensitive to the preaching of the Word. In this the sinner is passive. But he is not a subject of the new birth without contrition, repentance and faith. In exercising these he is active. Yet even his contrition is but a response to the Spirit's conviction, and the exercise of his repentance is but a response to the Spirit's conviction, and the exercise of his repentance and faith are but responses to the antecedent spiritual graces of repentance and faith." Carroll goes on to state that "repentance and faith are fruits of regeneration" (An Interpretation of the English Bible, Volume 4, p. 287)."
