Isaiah 30:21 ESV
And your ears shall hear a word behind you, saying, “This is the way, walk in it,” when you turn to the right or when you turn to the left.

Signposts are necessary to order in every society, without them, it would be utter chaos to achieve anything in any sphere of humanity.
Signposts are objects that give all kinds of public or private notices to society.
There are all kinds of signposts; verbal, written or pictorial signs that give instructions and order.
Everyone needs a sign to help them navigate their day easily, smoothly and orderly, we depend on signs to get to the right places, do the right things, and understand things better and who or what is needed for certain things.
Signs show us: detours, one-way, construction sites, curves and narrow roads ahead both physically and spiritually.
There are signpost instructions that every motorist will appreciate, heeding these instructions will help people avoid getting into unsafe situations because it tells them how to act on the road for the safety of everyone.
In the Christian walk, Jesus is the Way and has shown us how we are to walk. We have His Holy Spirit to lead and guide us in the way we should go, the narrow way that leads to life and not the broad way that leads to destruction.
There are spiritual signposts that instruct us on how to stay under God’s protection. If you will heed these signposts, you can safely remain on the right course.
The Lord says when we need directions in life, He will tell us where to turn, either to the right hand or to the left, because He’s the covenant God to those who love Him according to Jeremiah 31:33.
Some people depend on astrological signs to guide them, some trust in tarot cards, some in tea leaves and many such things but you have the most accurate, up-to-date and infallible word of God in manual form, the bible for a sign says 2 Timothy 3:16.
We must learn to investigate God’s word for the sign we require, although the Lord will prefer you to trust Him on His word because He will bring it to pass in time as promised in Jeremiah 1:12.
God will use whatever means He likes to gain our attention but be assured that whatever He uses will come from His word, always match whatever sign you ask or look for against the word of God to be sure that you are aligned with the word of life and truth.
For there is no other name, direction, route, way, or person, by which we can do anything but by the name of Jesus according to Acts 4:12.
From the beginning, people have tried all sorts of signs to approach God or seek answers, such as,
Astronomical signs in Revelations 6:12.
Babies for a sign- Isaiah 7:14.
Miraculous signs- 2 Corinthians 12:12.
Men as signs- Zachariah 3:8.
Prophetic sign- Exodus 3:5.
Signs are needed but must be sought within the word of God. God says to ask for signs for yourself from Him in Isaiah 7:11 but we don’t necessarily get a sign if our motives are wrong as with the Pharisees asking for one in Matthew 16:4.
The enemy is determined to trip us up, so, be sure you look out for and obey the signs to avoid falling into his trap. 1 Peter 5:8. Obey the sign.
Shalom
