Paul extolled –

All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness. Let the Word of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual songs, with thankfulness in your hearts to God.   2 Timothy 3:16; Colossians 3:16

John Piper exhorted –

For me, the glory of God and the word of God are inseparable. I have no sure sight of God’s glory except through his word. The Word mediates the glory, and the glory confirms the Word.

Dallas Willard wrote –

Bible memorization is absolutely fundamental to spiritual formation. If I had to choose between all the disciplines of the spiritual life, I would choose Bible memorization, because it is a fundamental way of filling our minds with what it needs. This book of the law shall not depart out of your mouth. That’s where you need it! How does it get in your mouth? Memorization.

Charles Swindoll encouraged –

I know of no other single practice in the Christian life more rewarding, practically speaking, than memorizing Scripture … No other single exercise pays greater spiritual dividends! Your prayer life will be strengthened. Your witnessing will be sharper and much more effective. Your attitudes and outlook will begin to change. Your mind will become alert and observant. Your confidence and assurance will be enhanced. Your faith will be solidified.
