But Jesus looked at them and said to them, "With men this is impossible, but with God all things are possible."
Jesus wasn't talking about what we consider to be miracles. He's not talking here about stopping rivers from flowing, or anything like that.
Jesus just finished up this conversation about wealth and the kingdom of heaven (The camel through the eye of a needle, which is kind of like our 'needle in a haystack'). Then the disciples got really confused, and wondered who would ever be saved.
Now, the disciples did something we do all the time to God. They subconsciously doubted Him. 'Obviously, that's not going to work' kind of thinking. These people saw Jesus feed thousands of people with only a few loaves of bread, walk on water, calm a storm, heal countless people... But this, this was above what they thought this Jesus could do.
But this is where our Jesus quote comes in. "With men this (salvation for a rich man, due to pride and not wanting to give away his money and such) is impossible, but with God, all things are possible". Anyone can be saved, anyone can come to Christ, because everything and anything is possible with God.
In His Service,
