You received your spiritual life by receiving Jesus Christ into your heart by faith. You live the Christian life in the same way, by trusting Jesus Christ to live His life in you, day by day, moment by moment.
Who may ascend the hill of the LORD? Who may stand in his holy place? He who has clean hands and a pure heart, who does not lift up his soul to an idol or swear by what is false. Psalm 24:3-4
