A Must Read For Every Christian
Format: Kindle
I first learned of the author, Arthur Meintjes, from Andrew Wommack's ministries. After listening to several of Arthur's messages, which are available at his Kingdom Life Ministries' website, I decided to purchase his book. The Kindle version is easy to read between my computer and my phone. The message Arthur presents is clear, God is not angry with me. Arthur along with the Holy Spirit has replaced my vision of God as a stern Judge that I must obey into God the Father who loves me. Since performance is not required for His love, I now can rest easy in His presence. My life is now dedicated to getting to know the Father through the Son with the guidance of Spirit. AMEN! Arthur, thank you such a wonderful book. May the Lord continue to bless you.

This is one of the best books I have read in years
Format: Paperback
This is one of the best books I have read in years. Arthur Meintjes is a joyful teacher who concentrates here on the essence of the Gospel. You will loose your "religion" and gain your rightful relationship with your heavenly Father with a renewed understanding. As a pastor I highly recommend this to churches, small groups, pastors (in particular) and anyone teaching others. In fact I recommend it to anyone who does not feel comfortable with God the Father. You'll find through scripture that our Father God is not the angry being that is always half ready to kill us, or that barely tolerates us, and find that Jesus was the exact representation of our Father, and this is Good News. Highly Recommended.

Intimacy with Father God!
Format: Kindle
Wonderful teaching on the relationship Gods the Father wants worth you; Jesus Christ as an example of that relationship—if you know Jesus, you know the Father and vice-versa. God the loving Father!
