We love Him because He first loved us. – 1 John 4:19
If the ardent love of some saints often takes the shape of admiration of God, this arises from their familiarity with God, and this familiarity they never would have indulged in, unless they had known that He was their friend. A man could not speak to God as to a friend, unless he knew the love that God hath toward him. The truer his knowledge and the surer, the closer his fellowship.
Brethren beloved, if you know that God has loved you, then you will feel grateful; every doubt will diminish your gratitude, but every grain of faith will increase it. Then as we advance in grace, love to God in our soul will excite desire after Him. Those we love we long to be with; we count the hours that separate us; no place so happy as that in which we enjoy their society. Hence love to God produces a desire to be with Him; a desire to be like Him, a longing to be with Him eternally in heaven, and this breaks us away from worldliness; this keeps us from idolatry, and thus has a most blessedly sanctifying effect upon us, producing that elevated character which is now so rare, but which wherever it exists is powerful for the good of the church and for the glory of God…It may help those who aspire to mount high in grace, if they keep in mind that every step they climb they must use the ladder which Jacob saw. The love of God to us is the only way to climb to the love of God. ~ C.H. Spurgeon
