Repentance is a fundamental concept in Christian theology, signifying a profound change of mind and heart, turning away from sin and toward God. It is not merely an emotional response but involves a conscious decision to forsake sin and pursue righteousness. The Greek word for repentance, "metanoia," implies a transformative change of heart and mind.

In the Old Testament, repentance is often associated with the Hebrew word "shuv," meaning to return or turn back. The prophets frequently called Israel to repentance, urging them to return to the covenantal relationship with God. For instance, in Joel 2:12-13 , the Lord calls His people to repentance: "Even now," declares the LORD, "return to Me with all your heart, with fasting, weeping, and mourning. Rend your hearts and not your garments. Return to the LORD your God, for He is gracious and compassionate, slow to anger and abounding in loving devotion."

In the New Testament, John the Baptist and Jesus Christ both began their ministries with a call to repentance. John the Baptist proclaimed, "Repent, for the kingdom of heaven is near" (Matthew 3:2). Similarly, Jesus emphasized repentance as essential for entering the Kingdom of God: "The time is fulfilled," He said, "and the kingdom of God is at hand. Repent and believe in the gospel" (Mark 1:15).

Repentance is closely linked to faith in the New Testament. It is a prerequisite for forgiveness and salvation, as seen in Acts 3:19 : "Repent, then, and turn back, so that your sins may be wiped away." The Apostle Paul also underscores the importance of repentance, stating that God "commands all people everywhere to repent" (Acts 17:30).

Repentance involves acknowledging one's sinfulness, feeling genuine sorrow for sin, and making a deliberate choice to turn away from sin and toward God. It is a continual process in the life of a believer, as Christians are called to live a life of ongoing repentance and faith.

Supplication

Supplication is a form of prayer characterized by earnest and humble requests or petitions to God. It is an expression of dependence on God, acknowledging His sovereignty and seeking His intervention in specific situations. Supplication is often accompanied by a sense of urgency and deep sincerity.

The Bible provides numerous examples of supplication, illustrating its importance in the life of believers. In the Old Testament, King David frequently engaged in supplication, as seen in Psalm 28:2 : "Hear my cry for mercy when I call to You for help, when I lift up my hands toward Your holy sanctuary." David's prayers often reflect a heart of humility and reliance on God's mercy and grace.

In the New Testament, the Apostle Paul encourages believers to engage in supplication as part of their prayer life. In Philippians 4:6 , he writes, "Be anxious for nothing, but in everything, by prayer and petition, with thanksgiving, present your requests to God." Here, supplication is presented as a means to bring one's concerns and needs before God, coupled with an attitude of gratitude.

Supplication is also a communal activity, as believers are encouraged to pray for one another. In Ephesians 6:18 , Paul instructs the church to "pray in the Spirit at all times, with every kind of prayer and petition. To this end, stay alert with all perseverance in your prayers for all the saints." This highlights the role of supplication in fostering unity and support within the body of Christ.

The practice of supplication underscores the believer's trust in God's provision and care. It is an acknowledgment of human limitations and a recognition of God's power to act on behalf of His people. Through supplication, Christians express their dependence on God and their confidence in His willingness to hear and answer their prayers according to His will.
