Not an offer? Tell Owen: "Wherefore, that which is now proposed under consideration in answer hereunto, is the readiness of Christ to receive every sinner, be he who or what he will, that shall come unto him. And hereof we have the highest evidences that divine wisdom and grace can give unto us. This is the language of the Gospel, of all the the Lord Christ did or suffered, which is recorded therein; this is the divine testimony of the 'three that bear record in heaven, the Father, the Word, and the Holy Ghost'; 'and of the three that bear witness on earth, the spirit, the water, and the blood:' all give their joint testimony, that the Lord Christ is ready to receive all sinners that come to him. They who receive not this testimony make God a liar,- both Father, Son, and Spirit."
God's call is sovereign, and this makes the importance of accepting the offer without delay even more important.
