Read Romans 9:6-18.
God can, and will, do whatever he wants to do. He cannot be manipulated or even completely “figured out.” And whatever he does is right.
While you’d be hard pressed to find a Christian who disagrees with any of those three statements, no small number of us have a hangup with those same thoughts applying to who can experience his salvation and how. But God’s Spirit moved Paul to write these words to remind us and bring total clarity to things:
“For he says to Moses, ‘I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.’” (vs.15)
Such was the case in the way God provided physical children for Abraham and Issac and it is, Paul says, equally true in the way he makes spiritual children of his own today.
God said it. I believe it. That settles it for me.
Father God, I thank you that you are not like me! You are wholly beyond finding out in totality. I don’t want or need a God I can completely get. I need a God bigger than me, superior to my way of thinking and far, far greater than my heart. And such a God you are! You must be the true and living God, for you do what you will and yet, you stoop down to rescue those who have repeatedly let you down! Such mercy and compassion, I can hardly fathom, but I gladly accept, rejoice in and will tell the world about! I thank you that my rescue doesn’t depend the impossible – me getting everything right. But I praise you for you always being right and caring for me, though I am so very often in the wrong. I will tell others often of this mercy that comes from you, and so, may like mercy flow through me, in Jesus’ name. Amen. And amen!
