God is not limited by time nor distance. He lives forever and is everywhere. As long as you open your heart to him, he enters to dwell within you. You could have been one who followed Christ while he was on earth 2,000 years ago; but if you hadn't allowed him to enter your heart, he remains outside of you. On the other hand, if today you who haven't even seen the Lord open your heart to him, he is all yours. God is always there, but we pass. Therefore, grab him while we can or we'll leave this world empty-handed.
