Being strong in Jesus Christ constitutes spiritual strength. It is the quality in a believer that makes him to tenaciously believe in the inspirational words of God especially when confronted with daunting situation. (Jack Zevada: www.christianity.about.com…strength) A unique example is the praise and worship songs of Paul and Silas in prison. Acts 16: 25-30. Their spiritual strength triggered off God’s earthquake that shattered the shackles, fetters and chains used to hold them bound. The same spiritual strength in them made them to boldly and honestly remain and waited for the jailor to see that they were not jail-breakers. They were fearless of what man could do. “The Lord is my light and my salvation; whom shall I fear? The Lord is the strength of my life; of whom shall I be afraid?” (Psalm 27: 1) God’s spiritual words are a source of strength to all believers. No doubt the jailed Apostles, in spite of their ordeal were so confident that load of fear did not manifest in them rather, by their spiritual strength, the jailor and the magistrate feared them. They could no longer prosecute them and therefore freed them asking them to go away from their territory.
In Isaiah 40: 31 we read: ‘Those who wait upon the Lord shall renew their strength. They will mount up with wings like the eagle. They shall fly and shall not be tired; they shall walk and not faint’. Eagle is a symbol of strength. In Isaiah 41: 10, the Lord said ‘Fear not for I am with you. Be not dismayed for I am your God. I will strengthen you, yes I will help you. I will hold you with my righteous right hand’. These are reassuring Words of God that infuse greater spiritual strength in one to be able to withstand the devil or adversaries. In Ephesians 3: 16, Paul psyched the Ephesians not to lose heart in “that HE (God) will grant you, according to the riches of His glory, to be strengthened with might through His spirit in the inner man” During Elijah’s flight away from Jezebel, even during extreme flight, God sent a raven to feed him with two meals which gave him strength lasted him for 40 days and 40 nights without eating. 1 King 19: 8 presented a vivid scenario of how “he arose; and ate and drank and he went in the strength of that food for forty days and forty nights as far as Horeb, the mountain of God”
What added up to become spiritual strength are namely, fear of the Lord, serving the Lord in sincerity and in truth; praying without ceasing; putting away of all idols; serving the Lord in the areas one is needed, reading and studying the bible along with memorizing verses for various life’s needs. It is also paramount that quotable quotes from Jesus Christ, David, Peter and Paul as well as many anointed servants of God like Isaiah, Jeremiah with other major and minor Prophets are needed to give a believer spiritual strength
