“But you, dear friends, by building yourselves up in your most holy faith and praying in the Holy Spirit,” (Jude 20)
Good communication builds up relationships. Information, encouragement, and wisdom are shared that each person may receive nourishment. Conflicts are settled appropriately and resolved in a way that the harmonious communication continues. Lack of appropriate communication hurts and hinders the connection between people. It does matters what is being said and how one saying it.
The Holy Bible states communication with God, prayer, builds one up. Faith or belief/trust in God is increased. A person grows to know God and His way. The Holy Spirit assists this communication. Believers in Christ have insufficient knowledge of what or how to speak to God so the Holy Spirit assists them. The mind and will of God is communicated to nourish the relationship.
Believer, rely on the Holy Spirit in prayer for building your relationship (faith) with God and the Lord Jesus Christ. God rewards such faith and fills you with Himself. Praise Him!
