What God has joined together let not man put asunder: Grace and truth? Repentance and forgiveness? Resurrection and the cross? Mercy and Judgement? Old and New Testament? Holiness and Mission? Personal faith and church commitment? Word and Spirit? Father Son and Holy Spirit? Suffering and glory? Humility and divine indwelling?
No doubt you can add to this or for that matter may feel you want to subtract from it. Let God guide the meditations of your heart.
