The narrow way is very narrow indeed.  In every moment, God directs, and we either yield to Him or resist Him.

Matthew 7:13 & 14 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 to life, and few there be that find it.

Strait is not the same as straight. Strait is an archaic usage and it means constricted. Narrow means narrow.

We never realized just how strait and narrow the way is. Whatever is not of faith is sin. That is Scripture. Faith comes by hearing and hearing comes by a word (literally, utterance) of God.

Unless your conscience has been seared by disobedience, you know the will of God. You may rationalize around it or contend with God, but you know His will.

Whatever is not of faith is sin and falls short of the glory of God.

God wants to lead us and He also wants to give us the power to follow His leading through the blood of Christ. Actually, that is an understatement.  The truth is that God wants to do His works through us.  If we will yield our members as instruments of His righteousness, then He will do His work through us. That is righteousness.

The gate is very strait [constricted] and that way is very narrow.

God does the work. Our part is to yield. We are to speak as the oracles of God, the mouthpiece of God. We are to see with the eyes of the Spirit. We are to bear the fruit of the Spirit.

If and when we fail, God forgives, because He sees us as the completed work. He also cannot be deceived.  He knows if we are repenting in a way that is insincere.  He knows our frame and He knows that He isn't finished with us yet. He also knows that He is well able to complete the work.
