"My father has it." Has it. Present tense. This is Mark Hamill's voice we're hearing, a.k.a. Luke Skywalker. And we all know who Luke's father is, and what happened to him. Luke's talking about the force being strong in his family, in him, his sister and his father. And this reference to his father, good ol' Darth Vader / Anakin Skywalker, in the present tense hints at Vader's possible return. Or maybe we'll just see Anakin in his Hayden Christensen form. After all, Christensen was edited into the end of Return Of The Jedi as Anakin's Force ghost, finally redeemed from his evil Vader ways. Christensen's Anakin is surrounded by hatred among most Star Wars fans, so it's hard to see him having much, if any, screen time. Officially there's been no mention of Christensen being involved with The Force Awakens at all. But why say Luke's father has the Force, unless you're going to do something with him?
