“Do not cast me from your presence or take your Holy Spirit from me.” (Psalm 51:11 NIVUK) This verse is truly “one in the eye” for those who suggest that Trinitarian theology belongs only in the New Testament. We hear how crucial is the Holy Spirit to King David; without Him, he is as nothing, and so are we. To try and follow Jesus Christ without the indwelling power of God’s Holy Spirit is impossible. Look at a balloon without any air or helium; it lies flat and lifeless on the floor. But, immediately it is filled, the balloon flies free and bounces around, bringing much joy. The PRESENCE of the Holy Spirit, Whom Christ promised to all who believe, is one of God’s greatest PRESENTS!
