well in the bible it states that god chastens those he cares before but as to answering your question no god is not punishing you for when god chastens his children you will both learn from it and be better for it though you may not like it when god is seeking for you to change he will tug on your heart to do something good, things such as your marital status or love life god does not force upon anyone and like wise he will not hinder you from such ideals I know the feeling im in my 20s and have not been on a single date or relationship in any form but that does not mean to be so is some punishment by god for what matters to him likewise jesus is to strive to live a righteous life if this for you is something you desire to be ,in a relationship or even married then do so,as long as this does not keep you from serving god and putting him first then you have nothing to fear I mean just think of david and solomon in the bible each one had hundreds of wives and concubines and god allowed it but it wasnt until they were disrighteous or went to serve other gods that he had a problem with them this question of yours is actually not that uncommon nowadays nor was it thousands of years ago many have wondered am I doing right for god,another person who shared such a question was abram and his wife sarai abram followed god faithfully all the while god promising that he would make of abram a great nation and later when god changed their names to abraham and sarah and said that they would have their first official blood child sarah laughed in her heart for both she and abraham were now an hundred years old and she thought that it perhaps what not possible for her to have a child but when god informed abraham of sarahs laughing and confronted her she knew it was true and believed and had isaac,so dont think that just because you are slightly old that god can not still bless you ive said many times our life span according to genesis is not one hundred as people so groan it is in fact one hundred and twenty so why not live to that age and try not to worry on such trivial matters as stated in acts, be careful for nothing,for god gives many blessings but worrying about them so much can keep you from doing what god has planned for you so dont start thinking this is the end for what your life can be when in truth your life has still just begun so live it righteously and gratefully for our live is but a vapour but alongside god it can be even longer,even job who went through a time of loss lived to see generations of family before he died so dont give up because If you take a look around youll find god has not given up on you,just try thinking on such blessings as are you alive,do you have family,are you financially doing well,do you have a form of home,do you have good health,do you have friends that support you through tough times,do you have a place of worship,do you have enough food, if you have these blessing in your life then god is there with you just try not to think on your woes so much because im sure god wants to further bless you but if you let yourself get dragged into a pit of despair then how can god bless you for in such a pit you cant move forward so do your best to move forward and youll find gods been waiting on you patiently to bless you with what is laid on your heart just go forward and accept what he's had waiting for you during your time of despair he knows we have troubles and trials and will give us the time to be melancholy but he also wants us to serve him while along the way obtaining all that is on our heart after all dont forget why did god make woman,because man was lonesome and god saw that despite all man had that he was sad so he made woman and from there on man and woman came together as one and were happy so its foolish to think that god would keep you from each other and its better to move forward and embrace what god has in store for all of us than to so often wonder if god is to blame for what ourselves have not truely strived for,simply do your part and god will do his part thats all there is to it
