John Wesley on 1 Samuel 12:14

Then, &c. - Heb. then shall - ye - be, (that is, walk, or go) after the Lord; that is, God shall still go before you, as he hath hitherto done, as your leader or governor, to direct, protect, and deliver you; and he will not forsake you, as you have given him just cause to do. Sometimes this phrase of going after the Lord, signifies a man's obedience to God; but here it is otherwise to be understood, and it notes not a duty to be performed, but a privilege to be received upon the performance of their duty; because it is opposed to a threatening denounced in case of disobedience, in the next verse.
