Can God use your life in 2015? Yes He can, but it must first be His to use.
Are you really saved --- not good, baptized, church member, but truly saved? If you don't know believe in Jesus with all your heart.
Are you fully surrendered to Him or are you holding back? Everything must be His.
Are you available for Him to use or is your life so cluttered with what you do that there's no room for Him?
Are you willing to be used by the Lord? He won't force you to serve Him.
With the New Year approaching, now is a good time to examine your heart and lay your life at the feet of Jesus.
Romans 12:1 I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service.
