This life offers only a window of time and opportunity to work for the Lord. Youthfulness and old age both offer their own hindrances to service. In many ways, though not entirely, youth should be spent in learning, middle age in doing, and old age in teaching those who are learning and doing. Many of the greatest servants of the Lord found in scripture began their journey in youth by learning of the Lord and His ways (1 Kings 18:12; Psalm 71:5; 2 Chronicles 34:3; Job 29:4; Ecclesiastes 12:1). As they approached the prime of life, they invested their learning by serving the Lord (Numbers 8:24-25). As they passed their prime, they would pass their knowledge on to the next generation in hopes of the Lord’s work continuing and flourishing (2 Timothy 4:1-8)..
Wisdom often results from time and experience. It should not, however, be assumed that old age automatically equals wisdom. For instance, the Bible says, “Better is . . . a wise child than an old and foolish king.” Wisdom comes from the Lord, and He distributes wisdom irrespective of one’s age. Perhaps the wisest statements given by man found within the Book of Job were given by a young man named Elihu (Job 32:6). He listened carefully as Job’s older friends spewed forth foolish words. He thought that “days should speak, and multitude of years should teach wisdom” (Job 32:7). Eventually, he came to the conclusion, “great men are not always wise: neither do the aged understand judgment” (Job 32:9).
Life is cyclical. Many of the physical challenges experienced by young children will once again be encountered by those who live long enough. As a person ages, many things taken for granted long ago in the prime of life begin to deteriorate. For instance, the Bible says that Israel’s eyes “were dim for age” (Genesis 48:10), Barzillai’s hearing and taste buds were ill affected (2 Samuel 19:34-35), and David “gat no heat” (1 Kings 1:1) as he grew old. For these reasons and others, the Bible emphasizes that aged saints are “old and well stricken in age” (Genesis 18:11). In other words, the passing of time or the coming of age strikes the physical well-being of the body and its physical and mental functions. This physical and mental degeneration is the fulfillment of the cycle of life as the body prepares to return to the dust from whence it originally came (Ecclesiastes 12:7).
There are people everywhere who are not saved, no matter where anyone lives. In addition to that, there may also be those who do not even have the knowledge of God. Unfortunately, many believers take for granted that all those who live in certain developed nations of the world have heard the gospel of Christ. This simply is not true. As fewer preach and teach the gospel of God’s grace, the number of those ignorant of these truths continues to increase exponentially. In addition to this, those propagating damnable doctrines continue to muddy the message of salvation. These realities increase the responsibility of true believers to be better ambassadors for Christ. Paul expressed these truths when writing to the believers in Corinth. He told them about the ignorance of some in their midst and put the blame squarely upon those who knew the truth and refused to witness.
The powers demonstrated by the apostles have consumed many Bible teachers who fail to grasp the place and purpose of those powers. These teachers instruct believers to seek the same power that was bestowed upon Peter and Paul and the other apostles. Careful Bible study demonstrates that the motive in this teaching is misplaced. The power given to the apostles was given for the purpose of assisting them in telling a lost and dying world about a risen Saviour. Much of the modern teaching centers upon pride and encourages a selfish Christianity. The biblical power given to the apostles was meant to strengthen their witness to others, not simply to be a self-serving instrument. Modern Christianity focuses on self, while biblical Christianity focuses on the Saviour and others.
In order to be saved, a person must place his faith solely upon Christ’s death, burial, and resurrection for the means of salvation. Paul defined this central body of truth as the gospel of the grace of God (1 Corinthians 15:1-4; Acts 20:24). Though believers may tell what the Lord has done in their lives since being saved, the most important truth when witnessing involves Christ’s crucifixion, death, and resurrection from the dead. This truth, the resurrection of the Lord Jesus, became the theme of the early church. A careful study of the evangelistic messages of the early church testifies to this fact. Just as this doctrine historically served as the central truth when dealing with the lost, it should continue to be so today.
In Bible times, cities would often build towers to watch the gates to avoid dangers looming from without (Isaiah 21:8). Watchmen would take turns watching the gate. These watchmen were responsible for sounding a trumpet should any danger appear (Ezekiel 33:6). The apostle Paul in his writings applied a spiritual application to this literal act of being a watchman. Just as cities needed men willingly staying awake and alert while others slept or were busy in their daily routines, churches need believers sober and watchful while others might be cumbered about with the cares of this world. Today’s watchmen must use their voices like a trumpet to sound the alarm when danger nears.
Dedicated soldiers are a dying breed, especially amongst Christians. Few people endure when the going gets tough or obstacles surface. The average Christian believes that God’s will involves no hurdles. In the secular world, drill sergeants, employers, and teachers spend a great deal of time and effort trying to instill discipline into those who grew up lacking character with little desire to succeed. This lack of character affects us all. Good soldiers endure hardness. They do not quit in the service of the Lord because of trials and tribulations. Neither do they allow themselves to be entangled in the affairs of this life. Their main desire is to please the very one who chose them to be a soldier in the first place.
Paul and Barnabas admonished the heathen to turn from “vanities unto the living God.” One cannot trust in the Lord and simultaneously trust in anything else. In order for an individual to be saved, he must repent of trusting in anything other than the Lord. One aspect of repentance involves ceasing to trust vanity and turning one’s faith toward the living and true God. This saving faith needs to become a living faith following salvation. Believers should consistently turn from “vain thoughts” and love the law of God (Psalm 119:113). They should turn from the vain labours that spend their strength for nought (Isaiah 49:4) and be “steadfast . . . in the work of the Lord” knowing that their “labour is not in vain in the Lord” (1 Corinthians 15:58). Additionally, believers should turn from “vain words” (Ephesians 5:6) and hold “forth the word of life” (Philippians 2:16).
The book of Ecclesiastes contains documentation of Solomon’s life experiment apart from God. He examined the worth of subjects involving happiness, wealth, labour, and death. Ultimately, he concluded that life “under the sun” (Ecclesiastes 1:14) was vanity. The word vanity means empty or meaningless. Though Solomon wrote extensively concerning vanity, he was not the only person in the Bible to declare the vanity of life. In fact, Solomon’s father David declared that “every man at his best state is altogether vanity” (Psalm 39:5). King David added that if both men of high and low degree were laid in a balance together, they would be “lighter than vanity” (Psalm 62:9). Thus, regardless of worldly accomplishments and accolades, a life void of God remains meaningless.
