Galatians 4. You and I have to make the same choice as the Galatians did. We can decide to do our best, and hope that God accepts it. That is the choice of Hagar, of Ishmael, of the letter, of Sinai, it is a choice to enslave ourselves.
Or, we can take God on his terms. We can say, God, I cannot do it myself. I trust in Christ and his finished work on the cross. I trust in your Holy Spirit to guide me in the Christian walk. And I trust in You, heavenly Father, to bring me into the inheritance you have planned for me.
LORD, we choose you on your terms.
