As a born-again, evangelical Christian, Dave's faith is the most important aspect of his life. That faith is based on the following principles:

The Word of God
He believes that the Bible is the fully inspired Word of God, without error in the original manuscripts, written under the inspiration of the Holy Spirit, and that it has supreme authority in all matters of faith and conduct.  
(2 Timothy 3:16; 2 Peter 1:20-21)

The Trinity
He believes that there is one living and true God, eternally existing in three persons, equal in every divine perfection, and that they execute distinct but harmonious roles in the work of creation, providence, and redemption.
(Genesis 1:1,26; Matthew 28:19; John 1:1,3; 4:24; Acts 5:3,4; Romans 1:20; Ephesians 4:5,6; 2 Corinthians 13:14)

God the Father
He believes in God, the Father, an infinite, personal spirit, perfect in holiness, wisdom, power, and love. He believes that God concerns Himself mercifully in the affairs of each person, that God hears and answers prayer, and that God saves from sin and death all who come to Him through Jesus Christ.
(Isaiah 40:28, Jeremiah 33:3, John 14:1-14,23, James 4:8, Romans 11:32-36)

Jesus Christ
He believes in Jesus Christ, God’s only Son, who was conceived by the Holy Spirit, and is fully God and fully man. He believes in Jesus's virgin birth, sinless life, miracles, and teachings. He believes in Jesus's substitutionary atoning death on the cross, bodily resurrection, ascension into Heaven, perpetual intercession for Jesus's people, and personal visible return to Earth.
(Isaiah 53; Matthew 1:18-25, 20:28, 28:6; Luke 1:26-38; John 3:16; Romans 3:24-26, 5:1, 9:5, 10:9; 1 Corinthians 1:30-31, 15:3, 15:14; 2 Corinthians 5:21; Ephesians 1:7 Titus 2:13; 1 John 2:2)

The Holy Spirit
He believes in the Holy Spirit who came forth from the Father and Son to convince people of their sin, Christ’s righteousness, the judgment to come, and to regenerate, sanctify, and empower all who believe in Jesus Christ. He believes that the Holy Spirit indwells every believer in Christ, and that The Holy Spirit is an abiding helper, teacher, and guide.
(John 16:8-13; 1 Corinthians 6:11; Romans 8:26-27)

He believes that all people are sinners by nature and by choice and are, therefore, under condemnation. He believes that Jesus Christ died on the cross for our sins as a substitutionary sacrifice for us. He believes that those who repent of their sins and trust in Jesus Christ as Savior are saved from condemnation by grace and regenerated by the Holy Spirit.
(Genesis 1:26-27, 3:1-24; Matthew 20:28; John 3:16; Romans 3:1-25, 5:12-18; Ephesians 2:8-9; 1 John 1:8-9)

Christ's Return
He believes in the personal and visible return of the Lord Jesus Christ to Earth and the establishment of His kingdom. He believes in the resurrection of the body, the final judgment, the eternal joy of the righteous, and the endless suffering of the wicked.
(Matthew 25:31-46; John 5:28-29, 14:1-3; 1 Corinthians 15:1-58; 2 Corinthians 5:10, Philippians 3:20; 1 Thessalonians 4:16-17, Revelation 11-15, 20:4-6)

Baptism and Communion
He believes that the Lord Jesus Christ has committed two ordinances to the local church: baptism and communion. He believes that Christian baptism is the immersion of a believer in water in the name of the triune God as a public declaration of their faith. He believes that those who take communion, which was initiated by Christ for commemoration of His death, should be believers walking in fellowship with Him.
(Matthew 28:18-20; Acts 2:38-46, 8:36-40, 10:47, 18:8; Romans 6:3-4, 1 Corinthians 11:23-29)

Life of a Believer In Christ
He believes that every human being has direct relations with God, and is responsible to God alone in all matters of faith. He believes that Christians should live for the Glory of God and the well-being of others. Believers should seek to realize for themselves and others full maturity in Christ, who lived a perfect life. Believers should be active and regular members of a church community, whose primary task is sharing the gospel of Jesus Christ with a lost world
(Matthew 28:18-20; John 15:1-13; Romans 3:19-26, 6; 1 Corinthians 12:13; Galatians 3; Ephesians 2:8-9; Hebrews 10:24-25)
