Psalm 119:102, "I have not turned away from your ordinances, for you have taught me," expresses the psalmist's faithfulness to God's laws and the reason behind that faithfulness. Let's break it down:

"I have not turned away from your ordinances...": This signifies a commitment and perseverance. The psalmist is stating that he has remained steadfast in obeying God's commands (ordinances). He hasn't strayed, backslid, or abandoned his adherence to God's rules.

"...for you have taught me.": This explains why the psalmist hasn't turned away. The reason for his faithfulness is that God Himself has been his teacher. God has imparted understanding and wisdom to him, making him aware of the value and truth of the ordinances. This teaching could come through various means:

Direct Revelation: The psalmist might have experienced direct encounters with God or profound insights.
Scripture: The psalmist studied and meditated on God's revealed word and received wisdom.
Experiences: Life experiences, guided by God, taught him the consequences of obedience and disobedience, reinforcing the importance of God's ordinances.
Guidance: The Holy Spirit has guided him into a deeper understanding and obedience to God's laws.

In essence, the verse conveys:

The psalmist's unwavering commitment to following God's laws stems directly from God's personal instruction and guidance. He understands that obedience is not just a matter of following rules but a response to divine wisdom and teaching. Because God has taught him, he recognizes the value and benefit of staying true to God's ordinances. He acknowledges that his ability to stay on the right path is a gift from God.

Key takeaway: It highlights the vital role of God's teaching in shaping our obedience. Understanding the "why" behind God's commands makes obedience more meaningful and sustainable. It's not just blind adherence, but a willing and informed response to a loving and wise God.
