Identify the advice is the way of the Lord

1 Kings 12:10-17
So the king did not listen to the people, for this turn of events was from the Lord, to fulfill the word the Lord had spoken to Jeroboam son of Nebat through Ahijah the Shilonite.
When all Israel saw that the king refused to listen to them, the answered the king: "What share do we have in David, what part in Jesse's son? To your tent, O Israel! Look after your own house, O David! So the Israelite went home.
The nation's history as recounted in Kings fully bears this out. In 11:13 God reduces the kingdom because Solomon has broken covenant and disobeyed his commands. And as Israel strays further and further from the law and worship of God, things go from bad to worse.  Internal strife weakens both kingdoms. The nation becomes prey to stronger neighbors, and is eventually devoured by the great powers.
Why?
Rehoboam listen to the advice of the younger set. It turned from the Lord to fulfill the word the Lord had spoken, and it is because Solomon has broken covenant and disobeyed God's commands.
How to identify the suggestion is right and follow the way of God? Keep our heart to observe the decree of the Lord and worship the Lord, focus on the Lord. Let the Holy Spirit to lead us.
When our heart away from the Lord then we can not identify the way of God.
How?
Always keep heart to the Lord and obey God's commands. Then I will know what is the way of the Lord, and what is good advice.
