Our Incomparable Companion
Loneliness will creep into every life at some point. However, believers are never truly alone because God has given us a permanent companion — the Holy Spirit. He is the Helper who is with us forever.
No one can truthfully promise always to be available to another person; the realities of time, distance, and even death can separate two people who would prefer to face difficulties together. Thankfully, by sending the Holy Spirit to live inside us, Jesus Christ keeps His promise never to leave or forsake us (Hebrews 13:5). This means that our Companion is greater than any human friend. Since He is a person of the Trinity, He is adequate to meet our every need. The Holy Spirit's foreknowledge allows Him to prepare our hearts and our minds for any situation. We need never dwell in uncertainty or inadequacy.
Human beings were never meant to live alone. God designed us to be complete only when we are indwelt by His Spirit, which occurs upon our salvation. We can choose to ignore the Holy Spirit, though. For example, some people stubbornly attempt to live the Christian life in their own strength or skip Bible reading when they find it inconvenient. That kind of life is marked by discontent: peace will be fleeting, and loneliness will feel like the heart's permanent resident.
The Holy Spirit is our parakletos, or companion who "walks beside." If we hold Him at arm's length, we distance ourselves from the Father as well. But if we ask the Spirit to guide our steps and open our minds to God's ways, He is available.
