Yes, A Christian Can Receive Jesus Christ As His Personal Savior And Lord Again And Again As The Salvation Becomes More And More Clearer To Him And Becomes More And More Heartfelt To Him. It Serves As His Recommitment To The Lord Our God And A Brand New Fresh Start All Over Again. Hee, Not That He Will Crucify Jesus Again As Said In Hebrews 6.but Rather A Recommitment To Jesus Because The Salvation Becomes More And More Heartfelt To Him.for When We Have Received Jesus As Our Lord And Savior For The First Time, And Continue In Him, It Becomes More Clearer Now That We Have The Holy Spirit In Us To Teach And Explain God's Word To Us.
