What is the promise of God's covenant?

The biblical narrative presents God's covenant as a binding promise that He makes, particularly with those elected unto salvation. Unlike human covenants based on mutual agreement, God's covenant operates under the terms of ‘I will, and they shall.’ This means that God actively works in the hearts of His people, granting them the necessary faith and repentance. The efficacy of this covenant is grounded in God's sovereignty, ensuring that all whom He has chosen will come to Him and cannot resist His grace, leading to genuine worship.
