Matthew Henry on Heaven

"This will be to the salvation of all who look for him; he will then perfect their holiness, their happiness; their number shall then be accomplished, and their salvation completed. Observe, It is the distinguishing character of true believers that they are looking for Christ; they look to him by faith; they look for him by hope and holy desires. They look for him in every duty, in every ordinance, in every providence now; and they expect his second coming, and are preparing for it; and though it will be sudden destruction to the rest of the world, who scoff at the report of it, it will be eternal salvation to those who look for it." Matthew Henry
