Hey Sweet, I'm an Asian myself (we're neighbours, you know
) and I can relate to what you are going through. Many of my friends have been pressurised by their parents and other family members into getting married, by the time they turn 25. In the case of girls, it is even earlier, say 22 or 23. I can understand how difficult it must be to withstand the pressure from your family, and I salute your courage and determination to stand strong thus far. All I can say is that you should try to hold out for as long as it is possible. In I Corinthians 10:13, Paul says that God will not allow us to be tried beyond what we are capable of handling. He also adds that with the trial, He also provides for a way of escape so that we may endure it. Now, I do not know what that 'way of escape' is for you during this testing time, but I am sure there is a window that God has in mind for you. Please continue to stay strong and determined. Also be reassured that, should things go out of hand and you do succumb to your family's pressure, you are not at fault for it, so long as you continue to hold your faith in God.
My late paternal grandmother and her two sisters had been brought up in the Christian faith by one of her aunts. But when the time came to marry, they were all married to grooms whom their parents had picked. Like her sisters, my grandma was also married to a Hindu in a Hindu wedding. But, she continued to secretly believe in the Lord and she continued to go to Church whenever she could. When my dad and his siblings were born, she made it a point to bring them up in the ways of the Lord. It took a few years of struggle, but eventually, her husband came to the Lord in his death bed.
Alternatively, could you consider moving out of your parents' house and/or city? I know a few of my friends who have warded off the pressure by becoming independent and moving out of home. I know this may not be easy for all girls, but is that a possibility for you?
