That is the mandate that was given before Christ went to be with His Father. Why don’t we act like it? Mainly, because of pride and selfishness. Christians, who should know better, judge people by the way they dress or how much money they have and sometimes even by the car that they drive. Would Jesus do that? Even when He could have been the judge of those who persecuted Him, He didn’t.
The way that we live and work is a reflection of Christ and His message regardless of the type of work that we do. This should be our goal, to be the best possible reflection of Him that we can be.
If you don’t know Christ, there are ways to get to know Him without becoming a member of a church. Just ask Him to come into your life, and to cleanse you of your sins. That’s it, or rather that is the beginning of it. Your life from that point on will change. As He says in the Bible, “Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you:” Matt. 7:7.
Many people mistakenly think that this means that anything that we ask for, we can get. Jesus was talking about wisdom and the knowledge of God, not “stuff”. Serving God can be and will be the most rewarding experience that you will ever have, if you will follow Him daily.
Going back to your old habits or addictions that were before will only cause you to lose your witness to others. Your salvation is secure if you were sincere about your commitment to Christ, but your service to Him will make a difference in other lives by following Him. You will find yourself wanting to be around other believers and you will likely seek out a church to attend before long which will strengthen your walk with Him.
Give Jesus a try, ask Him into your heart, serve Him through your life. Others will benefit from your witness and they will be a blessing to you as well.
