Pray specifically for the Aku of Sierra Leone

These have indeed an appearance of wisdom in promoting self- made religion and asceticism and severity to the body, but they are of no value in stopping the indulgence of the flesh.
readColossians 2:23

Pray for those without Christ, that they will see the emptiness of human traditions and turn to the truth and grace found in Jesus.

Simon Peter replied, “You are the Christ, the Son of the living God.”
readMatthew 16:16

Pray that many will see clearly that Jesus is the Christ, the Son of the living God, and put their trust in Him.

This mystery is profound, and I am saying that it refers to Christ and the church. However, let each one of you love his wife as himself, and let the wife see that she respects her husband.
readEphesians 5:32-33

Pray that as people place their faith in Christ, they will grasp the profound mystery of Christ's love for the Church, reflecting this love in their marriages.

For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.
