Hebrews 4:12(ESV)For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart.
The Bible is inspired, inerrant, and infallible in its original autographs. It is the final authority and is perfectly able to guide and direct us in all matters (2 Timothy 3:16-17, 2 Peter 1:21, Hebrews 4:12, Psalm 119:160)
There is one God consisting in three persons; the Father, the Son, and the Holy Spirit. The three persons, while fulfilling distinct roles, are equal in power and glory. (Genesis 1:1;Matthew 28:18-20; Matthew 3:13-17)
Jesus Christ is fully God. He is the visible manifestation of the invisible God. That He came in the flesh and was found in the appearance of a man in no way diminishes His deity. (Colossians 1:15,19; 2:9; John 1:1-5; Philippians 2)
The atoning death of Jesus Christ is perfectly sufficient to cover the sins of any and all who “confess with their mouth that Jesus Christ is Lord, and believe in their hearts that God the Father raised Him from the dead”. While it is perfectly sufficient to cover the sins of everyman, it is only effectively applied to those who call Christ Savior. (Romans 10:9-10; John 3:16; Romans 3:25; 1 John 4:10)
The Holy Spirit is the third person of the Godhead equal to the Father and the Son in substance, authority, and glory. That the Spirit is a person and not a force is seen clearly in God’s Word which informs us that He has knowledge, has a mind, has a will, and other characteristics associated with person-hood. The Spirits work includes, but is not limited to, convicting the world of sin, regenerating the believer, convicting us of sin, sanctification, and equipping the believers to accomplish God’s redemptive work in this world. (1 Cor 2:10-11, Romans 8:27, 2 cor 5:17, Ephesians 4:13)
The church is made up of those from every nation who “confess with their mouth Jesus Christ is Lord and believe in their hearts that the Father raised Him from the dead” (Romans 10:9-10). The purpose of the church is to worship and glorify God while bringing forth His message of salvation with loving conviction (Matthew 28:18-20; Ephesians 4:15-16)
The personal return of Christ is what is known as the Second Coming. This will be when Jesus comes back in His perfected resurrection body with the church to reign for the Millennium. This will happen after the Rapture of the church and after 7 years of tribulation. (Revelation 19-20; 16:27)
