Psalm 119:169 May my cry come before you, Lord; give me understanding according to your word.
Prayer is not something we just say and hope for the best – prayer is our personal communion with Christ.
If you just don’t know what to say or ask for in your prayers, then wait on the Holy Spirit to guide you and give you understanding of what you need to ask for.
We have many examples of how to pray in our bibles, but sometimes you mind just goes blank and you forget those examples – then is the time to call on the Spirit to guide you.
