What? I wish there was a magic rule that made this easy. I'm afraid, there's none. But I do have a formula that I followed when I chose my better half, a decade ago. I was bombarded, just like all of us, with so many options and distractions that I started panicking.
My fear was not about making the wrong choice, but believing a wrong choice to be God's will
That is a scary statement to make and believe me, much more devastating if it becomes a reality. I have sat across young people shattered because they chose the wrong person, while they always believed that person to be someone of God's choice.
I am in the process of making a video that explains my formula, that could probably help you evaluate your choices and probably end up with the person of your dreams, blessed by God!
