Jesus tells the parable of the “unjust judge”, which is really a parable encouraging us “always to pray and not lose heart.” God is not an unjust judge that ignores our prayers. Instead He wants to have a relationship with us, wants us to communicate regularly with Him and persistent prayer is an important part of that.
The words Solomon wrote are easily applicable to our relationship with God, “be attentive to my words…keep them within your heart. For they are life to those who find them, and healing to all their flesh.” God’s word and regular prayer help us to run this race, and not lose heart.
