In times of extreme pressure and stress, when circumstances seem beyond our control, we often cry out to God, saying, Lord, give me strength! This plea encompasses not just physical endurance, but also mental and moral vigor, and above all, spiritual fortitude. God is the ultimate source of our strength, as declared in Psalm 68:35: The God of Israel is He who gives strength and power to His people. Blessed be God! Through His Spirit, He equips us to resist the selfish pulls of our nature, strengthening us as we train and discipline ourselves. Mentally, we must gird up our minds, remaining sober and hopeful in the grace revealed through Jesus Christ, resisting the secular pressures that aim to weaken our resolve. God grants us a spirit not of fear, but of power, love, and a sound mind, as affirmed in II Timothy 1:7, enabling us to withstand the influences that seek to bring us down. By engaging with His Word, reading, absorbing, and practicing it, our mental strength grows. Morally and spiritually, we face a daily barrage of immorality and societal decay, influenced by dark forces and wicked powers in high places. To stand firm, we must don the whole armor of God, relying not on our own might but on the strength He provides. As David proclaimed in Psalm 18:2, The LORD is my rock and my fortress and my deliverer; my God, my strength, in whom I will trust; my shield and the horn of my salvation, my stronghold. We are called to resist these evils, trusting in God's supply of spiritual strength to overcome the prevailing cultural tide. Each day, we must strive to be strong, using our physical, mental, and spiritual capacities to worship and glorify God, resisting distractions and pressures, and moving forward with the strength He grants us to achieve victory over the forces arrayed against us.

Fasting, though it deprives the physical body of strength, serves as a powerful spiritual exercise that adds conviction and depth to the inner man. In Ephesians 3:16-17, the desire is expressed that He would grant strength through His Spirit in the inner man, so that Christ may dwell in hearts through faith. Strengthening this inner man demands intense effort, as spiritual exercise cannot be passive but requires struggle and exertion. Jesus Christ and the apostles emphasize that such effort is vital for conversion and maturity, with Jesus indicating that only those who strive fiercely will take the kingdom by force. In the continuous struggle against the flesh, as described in Romans 7:14-24, the battle against sin's captivity builds spiritual strength through repeated resistance, much like physical training. Fasting becomes a vigorous spiritual exercise, a personal combat against the intense temptations amplified by satan the devil. It actively affirms to God a choice for a spiritual future over a mere physical existence, compelling a cry for both physical endurance and spiritual energy to overcome temptation, as reflected in Psalm 138:3 where strength in the soul is granted upon crying out. Building godly character, the strength of the inner man, involves resisting the downward pulls of human nature, akin to building physical muscle through resistance. Fasting mirrors this by tearing down old, enslaving habit patterns, as noted in Isaiah 58:6, to loose bonds and break yokes. This process requires submission to God after personal effort, allowing spiritual muscle to regenerate. Fasting demonstrates helplessness and dependency, acknowledging the need for God's Holy Spirit to replace carnal pulls and build holy character through a combined will to follow His law. Jesus Christ, in Matthew 4:2, gained strength for confrontation with satan through a 40-day fast, setting an example of resisting fleshly appetites. Fasting is a necessary tool to frame the mind to resist evil and do good, especially in spiritual struggles where certain challenges require prayer and fasting to overcome, as warned in Matthew 17:21. A regular program of fasting and prayer provides the strength to resist satan's way and grow in God's image, essential in the life-and-death battle against spiritual adversaries.

The concept of spiritual strength, often described as having "heart," is central to a transformative and enduring faith. Having heart goes beyond mere human will; it embodies faithful conviction, courage, determination, and hope that propel us to achieve extraordinary things and persevere through challenges. Biblical figures like Noah, who built the ark despite persecution, Moses, who led the Israelites through the wilderness, David, who defeated Goliath against all odds, Daniel, who remained faithful in adversity, and Shadrach, Meshach, and Abed-Nego, who faced the fiery furnace, all exemplified this heart—demonstrating unwavering commitment to God. Spiritual strength finds its true source in God, as expressed in Psalm 73:23-26, where the psalmist acknowledges that though flesh and heart may fail, God is the strength of the heart and an eternal portion. When our hearts falter, God fortifies us with His indwelling Spirit, providing the spiritual power to sustain us. This divine strength transforms hearts, as seen in Ezekiel 36:26-27, where God promises a new heart and spirit, replacing a heart of stone with one of flesh, enabling us to walk in His statutes. Obedience from the heart is crucial for spiritual stability, as highlighted in Romans 6:17, where Paul commends the Romans for obeying from the heart the doctrine delivered to them. This wholehearted obedience engages the entire person—mind, heart, and will—ensuring a stable and complete spiritual life. Deuteronomy 6:5 reinforces this by commanding love for God with all heart, soul, and strength, a principle echoed in Matthew 22:37-39 by Jesus Christ, emphasizing total conviction in living God's way. God desires a complete response, not a partial one, as reiterated in Deuteronomy 10:12 and Joshua 22:5, where serving Him with all heart and soul is required. Spiritual strength also involves the transformation and renewal of the mind, as described in I Corinthians 1:10, where unity in mind and thought through Christ brings peace and stability. Ultimately, God works to perfect us, as seen in Colossians 4:12, equipping us through His Spirit to stand complete in His will, striving toward spiritual maturity and wholeness. This journey of spiritual strength culminates in praising God with the whole heart, as David does in Psalm 9:1-2, reflecting a life fully dedicated to Him.
