Greater in number.
Though he was God, Jesus was also a man, and limited to one time and place. Of course, we too can only be in one place at a time, but we can travel widely; take planes, boats, trains, buses to many places to preach the Gospel. We can also use the internet, send Bibles and Christian books electronically, and use things like Zoom, Face time and other things to meet other Christians and have prayer and fellowship. Or write blogs, articles, or Christian books.
Jesus is everywhere now, through his Spirit. He is in all of us as we go out to witness for him and take his light to the world.
