How can we know that what we believe is true? Is Christianity just some made up religion? Is the birth of Jesus just another story we tell to children along with Santa Claus and the Easter Bunny? This sermon series looks at Gospel of Luke. Right at the beginning of his book, Luke tells us he is writing "so that you may know the certainty of the things you have been taught." Throughout his gospel, Luke is meticulous in providing proof for the authenticity of what is being recorded. I pray that this sermon series on this incredible account of the birth, life, death and resurrection of Jesus Christ will encourage and challeng us to be certain of who Jesus is and the salvation he has purchased for us through his death, burial and resurrection.
