Trials always change our relationship with God. Either they drive us to Him, or they drive us away from Him. The extent of our fear of Him and our awareness of His love for us determine in which direction we will move.
God’s love to us cannot fail any more than His love to Christ can fail.
God in His love always wills what is best for us. In His wisdom He always knows what is best, and in His sovereignty He has the power to bring it about.
