God's kindness, mercy, love and goodness, will always remain the same for those who sincerely believe in Him, in His salvation, and desire to follow Him. Everything else in this life is unstable and cannot be depended upon: riches do not last, friends often forsake us, our health inevitably gives way to various sicknesses and finally to death. But God, our gracious and merciful heavenly Father who loves us in Christ our dear Savior, remains unchanging and His gracious promises stand fast. He will continue to bless and keep us at all times. This should serve to strengthen our faith in Him and His Word so that we continue, year after year, to place all of our confidence and trust in the unchangeable God and in His unchangeable Word of Truth.
O Thou, who changest not, abide with me!
