I have searched the transcriptions of Goudhurst parish registers that I have and found the marriage you refer to;
1750 Oct 9 Jacob LUCK & Mary? REYNOLS by Banns [as transcribed]
However I cannot find the baptism of Jacob LUCK in 1725. LUCK is a popular name in Goudhurst, especially from the 1730s onwards, and there are many Jacob LUCKs, but not one at around that time. (In fact there was no child with the name Jacob of any surname baptised in Goudhurst from 1655 until the child in 1760, the son of your Jacob - see below). Perhaps he was baptised in a different parish?
Children of Jacob & Mary baptised at Goudhurst were;
1751 Jul 19 Mary D of Jacob & Mary LUCK
1753 Dec 25 Ellizabeth D of Jacob & Mary LUCK
1760 Nov 16 Jacob S of Jacob & Mary LUCK
1761 Dec 25 Thomas S of Jacob & Mary LUCK
1763 Dec 16 Jacob S of Jacob & Mary LUCK
1764 May 21 Walter S of Jacob & Mary LUCK
1766 Apr 16 William S of Jacob & Mary LUCK
I can also see 8 children baptised to Isaac and Elizabeth LUCK from 1736 to 1753.
