The only limits to prayer are the promises of God and His ability to fulfill those promises.

The conditions of praying are the conditions of righteousness, holiness, and salvation.

Prayer is a trade to be learned. We must be apprentices and serve our time at it. Painstaking care, much thought, practice and labour are required to be a skillful tradesman in praying. Practice in this, as well as in all other trades, makes perfect.

Those who know God the best are the richest and most powerful in prayer. Little acquaintance with God, and strangeness and coldness to Him, make prayer a rare and feeble thing.

We can never know God as it is our privilege to know Him by brief repetitions that are requests for personal favors, and nothing more.

Trouble and prayer are closely related. Trouble often drives men to God in prayer, while prayer is but the voice of men in trouble.

Holy living is essential preparation for prayer.
