A Christian is called to enter into the Kingdom of God by the strait gate at conversion, but we must walk the narrow way all our journey through. Here is instruction for believers to keep walking in the way of righteousness.
Matt.7.13-14Enter 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.
