Our friendship with God is sustained and developed through a continuous conversation (1 Thess. 5:17). Jesus reminds us that it is the ‘pure in heart’ who ‘will see God’ (Matt. 5:8). Such purity, a condition where no malice abides and full attention is given to God, is itself a product of our own consideration of how we perceive our relationship with God. David, ruthlessly pursued by Saul and in fear of his life, makes his appeal to God on the basis of his purity of heart.
