If you want to know Him, if you want to know His smile, if you want to know something about this living realization that God is your God and that He has loved you “with an everlasting love” (Jer. 31:3), that you are His child and that He will never leave you or forsake you (Heb. 13:5)—if you want this living witness of the Spirit, this ultimate assurance that is given through the love shed abroad in our hearts, going upward and back to Him in praise, worship, adoration, and thanksgiving, then begin to praise God for what you have.
Praise Him for everything—for the gifts of life and health and strength. Many people are ill and laid aside and cannot attend a place of worship. Do we thank God for our health and strength, our faculties, for all these gifts that He showers upon us so constantly and so freely? Thank God! David, of course, keeps on repeating this: “Because thy lovingkindness is better than life, my lips shall praise thee. Thus will I bless thee while I live: I will lift up my hands in thy name … my mouth will praise thee with joyful lips” (Ps. 63:3–5). And on he goes, even down to the last verse where he says, “The king shall rejoice in God.”
