12 Therefore strengthen the hands which hang down, and the feeble knees, 13 and make straight paths for your feet, so that what is lame may not be dislocated, but rather be healed. (Hebrews 12:12–13, NKJV)
Isaiah described Zion (Messiah’s kingdom) as a time when weak hands are strengthened, and feeble knees made strong (Isaiah 35:3). In Zion, straight paths for our feet are established by God’s word, from which we must not to turn to the right or to the left to do evil (Proverbs 4:26-27). Since we have come to Mount Zion and are redeemed by the blood of the reigning Lamb of God, it is no wonder Christians are now exhorted to do these very things (Hebrews 12:22-24; Revelation 5:8-10). Let us lift a discouraged Christian by bearing his or her burden (Galatians 6:1-2). Let us exhort a disciple who has stumbled along the path to repent and return to the right way of truth (Acts 8:18-24). Let us refuse to compromise with sin by warning those who stray into paths of error and immorality (Revelation 2:20-23). Strength in the kingdom of Christ is measured by service, not by being served (Mark 10:42-45). So, commit yourself to strengthening your fellow Christians and being a blessing in their lives. “Now we exhort you, brethren, warn those who are unruly, comfort the fainthearted, uphold the weak, be patient with all” (1 Thessalonians 5:14).
