Matthew Henry comments, “Those, and those only, who put on the Lord Jesus, and to whom he is all in all, have wedding clothes.” Personal, saving trust in Christ is necessary to be a part of His banquet. Such faith perseveres until the end of life by feeding on the Word of God preached and read and the Word of God made visible in the sacraments. Take time daily to pray for consistency in your faith and make use of the means of grace to strengthen your trust in Jesus.
