Gospel singer Marvin Sapp says up to now he still misses his wife MaLinda, who died of colon cancer in September 2010. On the 49th anniversary of her birthday, he wrote a lengthy social media post to describe what true love really is.

"Real love is about finding or being found by the person that will stick with you through the thick storms and the thin victories," he wrote on his Facebook page. "Real love doesn't just take sacrifice; it is based on sacrifice. Real love is founded on the notion that sometimes you may have to give part of yourself to someone else in order for them to be able to make it through, with the understanding that this person will do the same thing for you in your toughest times."

Sapp then gave his fans some advice when it comes to love and relationships. The singer believes that people should not settle for someone they do not deserve just for the sake of being in a relationship.

"Never allow yourself to remain in a relationship in which a person has proved over and over again that they aren't about this 'real love', because in short you are only wasting your time," he said. "Find that person or be found by a person who is going to be there to pick you up when you fall, and not just there for you to help them when they do the same. Don't pretend, find someone that you can trust, someone who is patient, and someone who seeks to understand."

Sapp added that he was blessed to have found that "real love" with MaLinda for 20 happy years, and their three wonderful children are a testament of their blessed union.

Before his wife passed away, Sapp recalled that she gave him the "greatest gift" of all. "She knew that there was nothing else that they could do. She literally said to me, 'Honey if you want me to be happy in my transition, promise me after I transition that you will live,'" he told The Christian Post
