Bible Concepts

Sanctification is a major concept in the Bible and refers to the process by which a person is made holy and set apart for God. The word itself means “to make holy” or “to set apart for a sacred purpose,” and it describes the transformation that takes place in the life of a believer after coming to faith in God (1 Thessalonians 4:3; Hebrews 12:14). Sanctification is therefore closely related to holiness, righteousness, and spiritual growth.

Satan is the chief spiritual adversary of God and His purposes and is portrayed throughout Scripture as a deceiver, tempter, accuser, and enemy of God's people. The name Satan means "adversary" or "accuser," while the New Testament also calls him the devil, meaning "slanderer." Although Scripture presents Satan as a real and powerful spiritual being, he is neither equal nor opposite to God. He is a created being whose power is limited by God's sovereignty. The New Testament presents the death and resurrection of Jesus Christ as the decisive defeat of Satan's power and promises his final destruction when God's kingdom is fully established.

Sin, in the Bible, is the fundamental problem of humanity and the root cause of separation from God. It is described as rebellion against God, a violation of His law, and a failure to live according to His will. Scripture defines sin plainly: “sin is lawlessness” (1 John 3:4), emphasizing that it is not merely wrongdoing in a human sense, but an offense against the character and authority of God.

Seventeen verses in the New Testament describe Jesus as the “Son of David.” But how could Jesus be the son of David when David lived about 1,000 years before Jesus?

Christians through the centuries have asserted that Jesus was the Son of God. However, his own declaration of this was not what led to his death.

Spiritual gifts are abilities and forms of service given by the Holy Spirit to believers for the benefit of others and the building up of the Church. The New Testament describes a variety of gifts, including teaching, service, encouragement, leadership, mercy, generosity, prophecy, healing, and others. No believer possesses every gift, and no gift makes one Christian more important than another. Like the different parts of a single body, believers are equipped in different ways so that together they may serve Christ, strengthen one another, and carry out the mission of the Church.

Spiritual warfare describes the biblical conflict between the purposes of God and the spiritual forces of evil. Scripture teaches that Satan opposes God, deceives humanity, tempts people toward sin, and seeks to hinder the work of God's kingdom. Christians are called neither to fear nor to become preoccupied with evil spiritual powers, but to stand firm in Christ. Their primary weapons are truth, righteousness, faith, the gospel, salvation, the Word of God, and prayer. The New Testament assures believers that Christ has already defeated the powers of evil through His death and resurrection and that their final destruction is certain.

The atmosphere is full of joy and anticipation, with families and friends dressed in festive clothing. The room is decorated beautifully and people smile while, at the same time, tears fill their eyes. What is it about weddings that produces these emotions in nearly all who attend?

Could it be that when watching the union of bride and bridegroom we are reminded of something for which we were made, and toward which we are headed?

The Church is the community of all who have been united to Jesus Christ through faith. In the New Testament, the word church most often refers not to a building but to God's people, called together to worship Him, proclaim the gospel, encourage one another, and serve the world in Christ's name. Scripture speaks of both the universal Church—all believers everywhere—and local churches that gather for worship, fellowship, teaching, prayer, and ministry. Christ Himself is the head of the Church, and believers are described as members of His body, each serving an important role in God's redemptive work.

The "fear of the Lord" is a recurring biblical expression describing a profound reverence for God that recognizes His holiness, power, authority, and righteous judgment. It does not ordinarily mean living in terror of God, but approaching Him with awe, humility, and a willingness to obey. Scripture repeatedly associates the fear of the Lord with wisdom, righteousness, and turning away from evil. For believers who know God's love and forgiveness, fear of the Lord becomes not a desire to flee from Him, but a reverent recognition of who He truly is.

The gospel is the "good news" that God has acted in Jesus Christ to save sinners and reconcile them to Himself. At the heart of the gospel are the historical events of Christ's death for sins, His burial, His resurrection, and His exaltation as Lord. Through His sacrificial death and victorious resurrection, Jesus accomplished what humanity could never achieve through its own efforts. The gospel is received by grace through faith, not by human merit or religious works, and it calls every person to repentance, faith, and lifelong discipleship. The New Testament presents the gospel as God's power for salvation and the foundation of Christian hope.

The Holy Spirit is the third Person of the Trinity, fully divine and eternally one with the Father and the Son. Throughout Scripture, the Spirit is active in creation, revelation, empowering God's servants, and accomplishing God's purposes. Jesus promised that the Holy Spirit would dwell within His followers, guide them into truth, and empower them for His mission. Following Pentecost, the Spirit's indwelling presence became a defining reality of the Christian life. He convicts of sin, brings spiritual life, produces godly character, gives spiritual gifts, and continually directs believers toward Jesus Christ.
