The blessings of the law are not canceled. Jesus confirmed the promise when He bore the penalty. If I keep the commands of my Lord, I may appropriate this promise without question.
This day I will come in to my house without fear of evil tidings, and I will come in to my closet expecting to hear good news from my Lord. I will not be afraid to come in unto myself by self-examination, nor to come in to my affairs by a diligent inspection of my business. I have a good deal of work to do indoors, within my own soul; oh, for a blessing upon it all, the blessing of the Lord Jesus, who has promised to abide with me.
I must also go out. Timidity makes me wish that I could stay within doors and never go into the sinful world again. But I must go out in my calling, and I must go out that I may be helpful to my brethren and useful to the ungodly. I must be a defender of the faith and an assailant of evil. Oh, for a blessing upon my going out this day! Lord, let me go where Thou leadest, on Thy errands, under Thy command, and in the power of Thy Spirit.
Lord Jesus, turn in with me and be my guest; and then walk out with me and cause my heart to burn while You speak with me by the way.
