You cannot grow spiritually and be a success in your Christian walk without developing a prayer life built upon the Word.
Born-again, Spirit-filled believers have within them, ready for use, all the power and ability they'll ever need to put them over in life.
When you have a need, find scriptures that promise you what you're praying about. Then you will have a solid foundation for your faith.
One day you'll stand in the fullness of God's blessings and purpose for your life. And you'll thank Him for those days of preparation.
No one can have an effective prayer life and have anything in his heart against another.
