This final section is a synthesis of what has gone on before. In it we read about what God does, what we do, what we desire, and how God responds to us. The whole of Psalm 119 is this: Let my soul live and praise You, and let your rules help me. It’s pretty simple, but oh, how hard it often is!
So what does God do? He gives us understanding, He delivers us, He teaches us, and He helps us.
Our role is to cry out, plead, praise, sing, choose, delight, and remember.
There are no excuses, extenuating circumstances, or circumstances that can interfere with our focus on the Lord. When we cry out, He gives understanding. When we choose His testimonies, He delivers. When we remember His commandments, He teaches. And when we praise and sing of Him, He helps us.
We must desire His salvation, seeking to abide in Him and longing for Him to find us when we go astray.
He responds to us according to His Word. His word is life (Philippians 2) and truth (2 Timothy 2). His word is both seed and sword (Matthew 13; Hebrews 4). And in Jesus, His Word is made flesh (John 1).
No matter how tumultuous the times or how complicated the circumstances, God is faithful to be with us. He speaks to us through His Word. When we remember His promises, we will live and praise Him with all that we are forever.
