Always in Prayer Not Losing Heart

Most Christians know and can shout hallelujah with the best of them when it comes to Proverbs 13:22, which says, "A good man leaves an inheritance to his children's children, but the wealth of the sinner is stored up for the righteous." However, many fall short in realizing their supernatural wealth transfer because they continue reading verse 23 in that same Proverb that says, "Much food is in the fallow ground of the poor, and for lack of justice there is waste." What is the key to ensuring that our just inheritance in Christ is realized and what spiritual posture guarantees it? It is found in the Parable of the Persistent Widow in Luke 18:1-8 that our Lord Jesus taught that men ought to pray always and not lose heart.
