1. The strength of His grace to empower. "My grace is sufficient for thee, for My strength is made perfect in weakness" (2Cr 12:9).
2. The strength of His arm to sustain. "Fear thou not, for I am with thee: be not dismayed, for I am thy God, I will strengthen thee" (Isa 41:10).
3. The strength of His love to inspire. "The love of Christ constraineth us" (2Cr 5:14).
4. The strength of His armour to protect. "Be strong in the Lord, and in the power of His might. Put on the whole armour of God" (Eph 6:10-11).
5. The strength of His joy to gladden. "The joy of the Lord is your strength" (Neh 8:10).
6. The strength of His Word to comfort. "This is my comfort in my affliction, for Thy Word hath quickened me" (Psa 119:50).
7. The strength of His power to qualify. "Ye shall receive power, after that the Holy Ghost is come upon you, and ye shall be witnesses unto Me" (Act 1:8).
