Psalm 116:10, I believed, even when I spoke: “I am greatly afflicted.”
Perhaps the greatest test of faith is believing God in spite of affliction. Not believing in God, but believing God. Believing what? A number of things He has spoken, but in particular His Word of forgiveness and justification of our sins. In other words, believe His promise, which was delivered to you through Christ on the cross. This is especially difficult in times of affliction and heartache. In such times, we don’t want to believe He’s gracious, compassionate, slow to wrath, steadfast in love, faithful, and forgives our sins (cf. Exodus 34:6-7). It takes insurmountable faith to say, “Lord, I know I am suffering, but I believe You.” For it is by nature that we don’t want to believe God—that is why it is so difficult for us to believe His promise. We hardly trust one another. Why would it be easy to trust God? But this concupiscence to rebel against God does not excuse the unbeliever or the one who loses faith. God is gracious and faithful indeed, but when He is far it is we who moved. Indeed, it is satisfactory to say with that father, “I believe! Help my unbelief!” And God is faithful to His promise. For even when “we are faithless, He remains faithful, for He cannot deny Himself” (2 Timothy 2:13).
