To believe on Jesus Christ with all our hearts appears to be one of the simplest acts imaginable, and to receive Him as our personal Lord and Saviour seems to present no great difficulty. Yet, in reality, before any soul actually submits to the Saviour, there has to be the working of God’s mighty power - AW Pink

'To believe on Jesus Christ with all our hearts appears to be one of the simplest acts imaginable, and to receive Him as our personal Lord and Saviour seems to present no great difficulty. Yet, in reality, before any soul actually submits to the Saviour, there has to be the working of God’s mighty power. In other words, a miracle of grace must be wrought in him. Before a fallen and depraved creature will voluntarily and unreservedly surrender to the just claims of Christ, before he will forsake his cherished sins and abandon his beloved idols, before his proud heart is brought to repudiate all his righteousness as filthy rags, before he is willing to be saved by grace alone, before he is ready to whole-heartedly receive Christ as his Prophet, Priest, and King, God must draw him by His mighty power. Nothing short of the exercise of omnipotence is sufficient.'
