When it comes to preaching or proclaiming the gospel to others, we can be in one of two categories. We can either be eager or ashamed. Now I realize that you may categorize yourself in the middle, but you should work toward going in the direction of EAGER! If you're not eager, then you're ashamed.
Romans 1:15-16 NIV "15That is why I am so eager to preach the gospel also to you who are at Rome. 16I am not ashamed of the gospel, because it is the power of God for the salvation of everyone who believes: first for the Jew, then for the Gentile." (italics mine)
eager - adj. - marked by enthusiastic or impatient desire or interest (impatient at delay or restraint)
ashamed - adj. - restrained by anticipation of shame (a consciousness of shame or guilt, i.e. embarrasment)
You and I should be eagerly looking for the opportunity to rescue the perishing instead of looking the other way when those around us are lost, hurting and dying.
Naturally speaking, what kind of human being would you be if you had a lifesaver and someone around you was drowning yet you didn't throw in the very device that would save his life? In the same way, you and I have the very thing that will turn their broken and tired lives around, yet we hesitate to dive in and rescue them.
Being ashamed will hold you back from not only sharing the gospel with others, but also from living life to your full potential. Break through the barrier of shame and recognize that what you have inside you is the POWER of God to rescue those in need.
