What is repugnant is the DISTORTION of the sovereignty of God, so that God is shown to undermine His own Gospel. The Gospel is all about the grace of God, not the sovereignty of God.
For the grace of God that bringeth salvation hath appeared to all men, Teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world... But after that the kindness and love of God our Saviour toward man appeared, Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost; Which he shed on us abundantly through Jesus Christ our Saviour;
That being justified by his grace, we should be made heirs according to the hope of eternal life. (Titus 2:11,12; 3:4-7)
According to those who distort the sovereignty of God, every mention of "grace", "kindness", "love" and "mercy" was a mistake made by the Holy Spirit. Those words should all have been replaced with "sovereignty"! And that is how the Gospel was perverted by men.
