Power belongs to God, and it is not merely that He is powerful, but that all power is His possession to use or distribute as He sees fit. We must know and believe this fact in a practical way to make the best use of His merciful warnings. A firm conviction in God's ever-present power provides the right perspective to not only endure challenging times but to grow, overcome, and witness for Him in the best way possible. God's strength is the source of our confidence, as seen in David's experiences in Psalm 59, where he finds safety in God and recalls His mercy toward those who serve Him. David attributes his strength and the dropping of his fear to God, calling Him his strength, and combines this with God's power and mercy to build his trust. In Psalm 62, David instructs us from his personal experiences why we can give God our fullest trust, especially as terrifying trouble builds with no place to run unless God supplies one. David describes God as our salvation, our deliverer from trouble, urging us to turn to Him first in times of need. He calls God our Rock, a source of stability, and our defense, with ways of deflecting attacks no human can match. God is also our glory, in whom we take pride for all that He is, and our refuge, a place of safety in any circumstance. David exhorts others to pray to God for help, affirming Him as a solid refuge in times of trouble, repeating five times in Psalm 62 that God is the only sure place of refuge. The supreme reason God can be fully relied upon is that all power flows from Him, and He gives it to whomsoever He wills. Whatever He wills, happens, and no one can nullify His attempts to accomplish anything in His creation. David emphasizes that God decides the outcome of whatever is in dispute, sitting in judgment of the whole earth. Power, or strength, encompasses not just brute force but intellect, wisdom, understanding, vision, logic, energy, eloquence, wealth, authority, privilege, control, mastery, persuasion, forgiveness, mercy, and more, making God superior to any other source of help. David suggests that when in trouble, we should go directly to the top, seeking God first, as there is no help like Him anywhere. God's power to act in behalf of His purposes forms the very foundation of our faith in Him, rendering Him the most trustworthy, as there is simply nobody more reliable.

God's strengthening is evident in the different spirit He placed within Caleb and Joshua, identified as His Holy Spirit, which supplied the courage and resolve needed to stand against the rebellion of the people and to maintain unwavering loyalty amid threats of stoning. This divine empowerment enabled them to view the fortified cities and giants not as insurmountable obstacles but as opportunities for God to act, since the same power that had already delivered Israel from Egypt and parted the Red Sea would again prevail. Throughout the forty years of wilderness wandering, God preserved Caleb's physical strength and inner patience, sustaining him without complaint until the time came to claim the promised inheritance. At eighty-five years of age, Caleb acknowledged that his continued vigor came solely from God's preservation rather than personal ability, and he approached the allocation of the land with confident reliance that the Lord would drive out the Anakim. The account illustrates that such strengthening flows from wholehearted obedience and dependence, allowing believers to persevere through trials, overcome seemingly impossible challenges, and fulfill divine promises by trusting in God's power rather than their own.

True power belongs exclusively to God, who alone exercises omnipotent sovereignty, and no one possesses authority unless He grants it. Jesus Christ shares this power, as do members of the church, enabling believers to accomplish all things through His strengthening. Scripture attributes power and might above all to God, evident in His creation and sustaining of the world, His mighty acts of salvation, and the names that describe Him such as El Shaddai and the Omnipotent One. When God delegates limited authority to humanity, He still intervenes with miraculous demonstrations of deliverance, as seen in the exodus from Egypt and the giving of the Promised Land. In the New Testament the emphasis shifts to spiritual application, where Christ exercises authority to forgive sins and cast out evil spirits, then extends this authority to His disciples. The greatest display of God's power occurs in the individual calling and conversion of believers. Christ promised the apostles power from on high at Pentecost, when the Holy Spirit became operative in the church. Paul prays that the Ephesians may know the exceeding greatness of this power toward those who believe, the same power that raised Christ from the dead and seated Him far above every principality. This power is not static but energetic and overcoming, the very energy of the strength of God's might at work within the saints. Paul presents two governing principles: the process of Christian conversion and salvation itself demonstrates God's power in us, for no one can make himself a Christian, and God alone creates new life; second, believers can be assured that this power is already operating because it is the same might that conquered death in the resurrection of Christ. This power produces a new disposition, imparting spiritual life where there was only death in trespasses and sins, renewing the inward person day by day, and supplying the capacity to overcome. Seven practical means advance God's strengthening: dependence upon Him in distress, the joy of the Lord that replaces sorrow, prayer according to His Word, the acquisition of wisdom that overcomes fear, quietness and confidence in His promises, patient waiting that renews strength, and reliance on His sufficient grace amid weakness. Because this power has already defeated every enemy, including death itself, nothing can separate believers from the love of God in Christ or prevent the completion of His purpose in them.
