Do you ask, "How am I to abide in Christ?"--In the same way as you received Him at first. "As ye have therefore received Christ Jesus the Lord, so walk ye in him" (Col. 2:6). . . . You gave yourself to God, to be His wholly, to serve and obey Him, and you took Christ as your Saviour. You could not yourself atone for your sins or change your heart, but having given yourself to God, you believed that He for Christ's sake did all this for you. By faith you became Christ's, and by faith you are to grow up in Him--by giving and taking. You are to give all --your heart, your will, your service--give yourself to Him to obey all His requirements; and you must take all--Christ, the fullness of all blessing, to abide in your heart, to be your strength, your righteousness, your everlasting helper--to give you power to obey. . . . {AG 293.3}

Your weakness is united to His strength, your ignorance to His wisdom, your frailty to His enduring might. So you are not to look to yourself, not to let the mind dwell upon self, but look to Christ. Let the mind dwell upon His love, upon the beauty, the perfection, of His character. Christ in His self-denial, Christ in His humiliation, Christ in His purity and holiness, Christ in His matchless love--this is the subject for the soul's contemplation. It is by loving Him, copying Him, depending wholly upon Him, that you are to be transformed into His likeness. {AG 293.4}
