I solemnly charge you in the presence of God and of Christ Jesus, who is to judge the living and the dead, and by His appearing and His kingdom: preach the word [as an official messenger]; be ready when the time is right and even when it is not [keep your sense of urgency, whether the opportunity seems favorable or unfavorable, whether convenient or inconvenient, whether welcome or unwelcome]; correct [those who err in doctrine or behavior], warn [those who sin], exhort and encourage [those who are growing toward spiritual maturity], with inexhaustible patience and [faithful] teaching. For the time will come when people will not tolerate sound doctrine and accurate instruction [that challenges them with God’s truth]; but wanting to have their ears tickled [with something pleasing], they will accumulate for themselves [many] teachers [one after another, chosen] to satisfy their own desires and to support the errors they hold, and will turn their ears away from the truth and will wander off into myths and man-made fictions [and will accept the unacceptable]. But as for you, be clear-headed in every situation [stay calm and cool and steady], endure every hardship [without flinching], do the work of an evangelist, fulfill [the duties of] your ministry. – 2 Timothy 4:1-5
The Spirit of God gives this gift to people in the church to strengthen and encourage those who are wavering in their faith. Those with the gift of exhortation can uplift and motivate others as well as challenge and rebuke them in order to foster spiritual growth and action. The goal of the encourager is to see everyone in the church continually building up the body of Christ and glorifying God.
Go therefore and make disciples of all the nations [help the people to learn of Me, believe in Me, and obey My words], baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe everything that I have commanded you; and lo, I am with you always [remaining with you perpetually—regardless of circumstance, and on every occasion], even to the end of the age. – Matthew 28:19-20
The most common word for encouragement in the Bible is “parakaleo”—“para” meaning “beside, near, with, along side,” and “kaleo” meaning “to call or summon.” A “paraclete” is someone called along side of another to counsel, encourage, help and bring comfort. This word is used to refer to the role of the Holy Spirit. When Jesus said to his disciples “I will not leave you comfortless” in John 14:18 he was saying, in effect, “I will not leave you encourage-less.” Paul referred to God as the God of encouragement (2 Cor. 1:4). The basic word is always used for one primary purpose—to describe functions that will help Christians be built up in Christ, or to help them build up one another in Christ. – Dr. Steven Riser
Such is the confidence and steadfast reliance and absolute trust that we have through Christ toward God. Not that we are sufficiently qualified in ourselves to claim anything as coming from us, but our sufficiency and qualifications come from God. He has qualified us [making us sufficient] as ministers of a new covenant [of salvation through Christ], not of the letter [of a written code] but of the Spirit; for the letter [of the Law] kills [by revealing sin and demanding obedience], but the Spirit gives life. – 2 Corinthians 3:4-6
