At one point or the other, most of us would have said to God to transform us into His own image, or transform us such that we will no longer have this or that bad habits. Sometimes, despite this, we even have our own "action plan"! We consciously decide that "I shall not do this from today onwards" but subsequently struggles and finding ourself doing just the thing we said we shall do no more of.
You see, when we become performance oriented, we fall back under law and not under Grace (Galatians 5:4)!
The bible says that transformation comes by beholding the Lord. When we focus on what we should or should not do, we are no longer beholding Christ but taking our eyes off what He has finished at the cross.
Just so you know, His eyes are always on you. He always watches out for you, and cares for you. He loves you deeply. So therefore, cast your cares on Him and rest in Him.
2 Cor 3:18
"18 But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as by the Spirit of the Lord."
Romans 10: 17
"So then faith cometh by hearing, and hearing by the word of God."
