Prayer
The most basic definition of prayer is "talking with God." Prayer is not meditation or passive reflection; it is directly speaking with God. It is communication of the human soul with the Lord who created the soul. Prayer is the primary way for the believer in Jesus Christ to communicate with and fellowship with the Lord God Almighty.
Philippians 4:6-7
6 do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. 7 And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.
