The undying love between two people is and as always been something special throughout the century. When it is strong from a spiritual level, it is compared to a three fold cord that just can not be broken. A love that is meant to be, that has been backed by God almighty, no one, can and will come between you and that special person to change how you each feel for each other. When your love is strong, you are going to be that much more determine to hold on to what you have, because again, God is in it, and he has got both of ya'll back. Constantly, you will always think about that person, and that is what Thinking About U is, that is the whole concept of the song.
