Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat: Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it. {Matthew 7:13-14}
A little pearl just jumped out at me from these words of Jesus. There is the Gate, and there is the Way, which lead unto Life. Many, many people respond to God's call and enter in at the Gate (the Door, the Messiah), but many of those forget about the Way. The word way means "a road; by implication, a progress; journey". Isn't that interesting?
Jesus is not only the Door. He is also the Journey beyond! We are to walk the Way, the Road, the Journey, that He instructed us to walk. If you have entered in at the straight Gate, don't just stand there. Walk! :)
