Whoever said the walk of faith was easy, lied! It isn't always easy, but it’s never impossible! We may suffer at times or fail and feel like quitting, but the Holy Spirit knows about it, and He helps us. The Holy Spirit knows we are prone to wander, and He helps us.
Romans 8:26 Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered.
We don’t always know the perfect will of God in every matter or how to pray, but The Holy Spirit knows the mind of God because He is God. He’s able to translate our prayers out of the flawed, selfish language we use into the perfect will of God. This is genuine, biblical praying in the Spirit.
We don’t know everything about the walk of faith, but this we do know:
Romans 8:28 And we know that all things work together for good to them that love God, to them who are the called according to his purpose.
